AMOLED Screens tend to differ from display to display, some users get displays presenting a warmer yellow color in presence of white while others get displays presenting a cooler bluish tint in presence of white.
Which presentation would you prefer in terms color appearances on AMOLED Displays (when using the Default Mode: Adaptive Display)? Warmer Displays or Cooler Displays?
I'll be honest when I say that 9300K "blue/cool" whites look more like true white to me, but the industry standards like sRGB, Rec. 709, etc. call for a 6500K "yellow/warm" white point and that leaves my hands tied when calibrating my displays for accuracy.
On that note, Android could use something like system-wide ICC profiles...
In Basic Mode, the display appears more yellow. However, in Adaptive Display, the display look "more cool."
Apart from these Modes, the displays are predisposed to a cool or warm tint, that makes the display appear either cool or warm (sometimes attributes to the pink or yellow tint in presence of whites).

I'll be honest. I've never taken the time to understand AMOLED Technology. It was more the active matrix part but I'll be the first to vote that I didn't.

I'm quite aware of the screen modes, but the white point color temperature and overall gamut (wider gamuts -> more saturation, deeper primaries) are only part of the whole color accuracy equation. The gamma is still far, far off from the 2.2 reference no matter what mode is used. Just open this up in your browser, then you'll wish you had some gamma adjustments somewhere on the Note 4. Maybe Lollipop will save us?

Overall, though, I'd say the most important thing is consistency, which is why standards exist. However, a lot of white LED-lit LCDs and such are much closer to those 9300K blue-ish whites. Mixing those up with some warmer 6500K yellow-ish whites is really jarring, and I can speak from experience there. I'd say for personal use, it doesn't really matter which you use so long as all your displays look consistent next to each other.
I prefer a bluer tint, but only slightly. None of this Xperia Z3 blow your face off blue.
I haven't seen a yellowish screen for a while though. The Note 4 I have leans towards Red or Blue and most other phones i've used lean from red to blue. Mainly red though.
I dislike 6500K, I always have.. For me 6500k white isn't white, it's yellow.

been follwing this for quite time and yes I agree with your post. Being on the note 3 camp , it's the same **** on our end. Recently encho
has been implementing KCAL to aid with changing our color temperatures. More developers should make it a standard to include KCAL in snapdragons.

I've noticed on my 8.9 Tab as with lots of recent other Samsung Tabs (the 7.7 included even though its an AMOLED) that the display basically has a yellow tinting.. no, actually, its all yellow. there are no whites in this tab, just yellow. Ive seen others on display at stores and to a more or lesser degree they are all like this. You can tweak somehow the display characteristics under the MODE in Display options but that really only makes it worse (choosing the MOVIE mode makes it even worse).
I had THE VERY SAME PROBLEM with my Galaxy Note (along with countless other people) but fortunately there is a app written for it that fully adjusts the RGB values, change the sharpness and color temperature for Dynamic, Standard and Movie modes. Its like magic and is not not a service or background process, its written permanently into the system's settings and done!
http://forum.xda-developers.com/showthread.php?t=1366280
Unfortunately this app doesn't not work with any other device Ive tried.
Now, there are a few (lame) apps on Google Play that allow for some degree of color correction but none of the really cut it.. by the time I add more Blue and Red and reduce contrast to tweak the yellow cast, lower gamma tinting appear and the yellow is still present. Is there a proper way to color calibrate the display on the 8.9 via software, editing props or changing code that gives instruction to the display hardware's characteristics?
The people at Samsung MUST be all blind to this on just about all their Tabs. I must say, as much as I detest the iPad, color-wise they are ALL always spot on! I am yet to see one that is yellow..
Thanks for the input!

VIEWER DISCRETION ADVISED
Bring the Brightness level down to minimum visible brightness (Preferably when viewing Near Grayscale); even in a well-lit room, or preferably dark setting, you will notice how Samsung managed to hide the Mura Effect on their latest iteration of AMOLED Panels. Some will see notice the predisposing lines, blobs, banding, and two-tone (or even more) gradients, which expresses the true organic nature of AMOLED Panels (Discussed as far back as the original Galaxy S phone).
Now beware, the Mura Effect is normal and does not make your screen or device defective.
Thanks to Samsung's preset for low Brightness levels implemented on the Galaxy S4, S5, Note3, and Note 4, and newer devices (can only be modified via third-party apps), its really hard to make out the Mura Effect on the newer models. Black color is Black, and Samsung's software mod forces no voltage to be fed to the AMOLED Panel when black is displayed, thus the pixels are literally turned off.
I've seen some users post pictures of the smearing (deep purple and pink tint) at "Normal" lower brightness levels (within Samsung's preset levels), which should be taken into account; I suggest them to exchange their devices or replace their displays until they get something better their eyes can be content with.
Every Note 4 and AMOLED device has these anomalies, however, the degree to which the anomalies are visible will vary from device to device. Some will be unable to make out the anomalies thanks to the nature of their displays (Warmer-toned or Cooler toned displays), and should be grateful and move on. If the anomalies are too obvious, I would suggest replace the screen, or live with it and accept AMOLED at its true best.
Downloaded the app and after messing around for a bit I can say that I am unable to make out the anomalies.
The screen quickly turns to black after messing around for a bit. It's good to know that Samsung has made "some" progress in alleviating some of the concerns most previous Galaxy device owners had particularly pertaining to AMOLED displays. However, we all are still far from seeing all AMOLED displays equal and consistent with one another. Some favor warmer colors whereas others favor cooler colors, and some in-between, thus variances will be prevalent until a final solution comes into play.

I switched from my LG V30 to a V40 about 3 day's ago.
I like the things they improved on the phone like the camera's and the reflectiveness of the screen / min brightness.
The thing that i dont like is the color reproduction i just cant get it right. Web gives the best colors but they are washed out compared to the V30 on Cinema. Moving to Cinema colors are blown out of proportion.
Manual settings have the same issue. Saturation neutral is still to much. One step lower is slightly washed out.
When i think i got red on the right value for pictures compared to the V30 a white screen looks red. If i fix that pictures look to green.
What settings do you guy's use?
Left it on 'Auto'. Never one to over-obsess with minor issues. The display is good enough to do colors on its own.
Sent from my LM-V405 using Tapatalk
Tried different ones Auto has been the best. It's a bit oversaturated but white point is good.
I see Auto setting still gives control over color temperature and RGB colors. You left those default? (neurtal and RGB maxed out?)
The cinema setting looks a bit more natural compared to Auto. (less overstaturation) And if i compare my picture to the real thing in real life the Cinema setting comes closer.
I believe I found better setting for myself to fix oversaturated display.
Expert mode, default color temperature, saturation and sharpness all the way down?
Found some extra information:
https://www.xda-developers.com/lg-v40-thinq-display-review/
Seems LG screwed up the Expert mode an almost all other color profiles. Googles does a better job using the same display.
Most accurate is the Web profile. Expert is not usable because color tempertature is above 7100K in all settings.
After web comes the Photo profile and after that Cinema. But that feels to overstaturated to me. While web lacks a bit of punsh. I guess that the UI was not made for the web mode and it looks understaturated because of that when using the web mode.
But for now i guess i will keep using web mode. I want to be able to see if the pictures that i take have the correct white balance and thats not possible in cinema mode. Faces look way to red. Same goes for photo but its less extreme.
Lets hope LG does a better job with the new android version later this year....
Out of the box the LG V40 ThinQ targets a cool and punchy color profile that is about 25% more saturated than our standard RGB color space. In the Auto and Expert profiles, it is possible to modify the display’s overall color temperature (albeit in a flawed manner) and to modify the relative reds, greens, and/or blues. The handset offers 6 other color profiles, and do provide profiles that accommodate the P3, Adobe RGB, and the sRGB color spaces. However, all three of the reference color profiles have a greenish-white point, and only the Web profile (which targets the sRGB color space) competently matches its target (though as seen in our Pixel 3 display analysis, LGD’s panels are completely capable of having near-perfect color accuracy with more adept calibration). Furthermore, none of the color profiles support Android’s color management, introduced in Android 8.0 Oreo, and even if it did, it wouldn’t mean much since almost no Android apps support it.
-------------------------------------------------------------------------------------------------------------
Starting at the profile with the most important color space to target, the Web profile does an alright job at reproducing the sRGB color space. However, as shown on the color accuracy plots above, the white point has a noticeable color error shifting towards green, which is also observable on the plot chart in the yellow, cyan, and cyan-blue color mixtures. Pure reds are also slightly oversaturated, but not too-noticeably so. Overall, the profile has an average color error ΔE of 1.7 and a maximum color error ΔE of 3.1 at 100% cyan-blue and 25% yellow, which is mostly accurate and acceptable for hobbyist-level sRGB color work in photos and video.
The Cinema profile, however, is not as accurate and contains a lot more colors with higher color differences. Almost all colors, besides the gamut primaries (100% red/blue/green), are oversaturated, and there’s noticeable error all throughout the reds, red-yellows, yellows, and greens. The white point shared with the Web profile is also too green. The profile has an average color difference that is considered just-noticeable (ΔE = 2.3), with a maximum error ΔE of 4.2 all around the red-yellow-green region. I would like to reiterate that this profile is meant for content that targets the P3 color space, and everyday use of it will result in content colors that will appear oversaturated.
The Photo profile is also not too good, beginning with the display’s green emitter not capable of reaching the full chromaticity of the Adobe RGB green primary; however, the 100% green color difference is not noticeable. Below 100% green saturation, however, there is noticeable color error with a high color error ΔE of 5.0 at 25% green. Yellows also show a lot of noticeable errors, a few other just-noticeable color differences are scattered throughout the gamut. The profile has an overall average color error ΔE of 2.1 (which is technically mostly accurate), but the high color errors the profile contains makes it unsuitable for color-critical work in the Adobe RGB color space.

My 10+ arrived yesterday and so far I've been impressed with two exceptions. As mentioned in other threads my finger sensor leaves a lot to be desired but my point of this thread was about an odd look my screen had. It was not bright and sharp like my 8+. There was a yellowish tint. I went into the 8+ to see if there were any differences in my display settings and I fixed the problem my by changing the screen mode on the 10+ from natural to vivid (Settings > Display > Screen Mode). The options were different on the 8+ but on the newer version it's one of the two, vivid or natural.
Just wanted to share that in case anyone else is having the same issue.
One question. My 10+ came with the screen protector and I've never had one. I assume they take away at least a small percentage of your brightness and clarity? I'm tempted to remove mine to see.

Keep in mind that Natural should follow the sRGB color space. Most displays have default colors that are too cold/blue (high color temperature, and I know, it's counter intuitive but that's what they call it ). Relative to "colder screens", sRGB will seem warmer / more yellow. But it's also much more accurate as far as color representation goes, and should be closer to what you see with your eyes unfiltered by sunglasses. This assumes whatever image you're looking at is also taken with neutral colors and not over saturated.
I usually calibrate all my screens to have more accurate colors, at the expense of that "pop" you can get with AMOLED screens.

That "pop" is exactly what I'm looking for so would you suggest I stick with vivid? I understand what you're saying about the colors but it's not an area I'm real familiar with. I'm just not seeing a brightness on the level I prefer and yes I have it set as high as possible.

Yeah, you'll want to leave it on vivid if you want that "pop". I also know that when my current Google Pixel got the Pie update, the auto-brightness was a bit finicky at first, as it's an "intelligent" brightness and it takes a few days to learn your preferences for the right brightness based on the lighting conditions. So that might be the case with the S10 as well, and I should be picking up mine tomorrow so then I'll know more about how it works exactly.
Also I think I read somewhere that the S10 will only get very bright in direct sunlight if it's set to auto-brightness. You apparently can't set it to that level manually. So perhaps play around with that a bit.
Any news on this? I just picked up my s10 plus and the screen has a yellow tint and seems less bright compared to my note 8...not sure if I just ask for a replacement. Thanks!
I always run mine on Vivid and WQHD and as expected the S10 is spectacular
Sent from my SM-G975F using Tapatalk
im surprised there isnt adaptive display mode like on the previous models this really made different colours pop. mine seems to have a bit of an orange tint
I also found it too yellow.. Go at the advanced settings and reduce the green close to the minimum and the red just a little bit. It will look white again..
Because of the sun light some people find yellowish colours more natural..
Yeah the whites don't look good on the s10 compared to my note 8
Just compared mine with different demo models and they all seem a bit more 'natural'. No need to swap it for a different one, allthough they all are a bit different...one more leaning towards blue white and the other to yellowish white.
Well coming from pixel 3, to me, Colors looks natural. S10 screen is crisp and clear. Nobody can best sammy when it comes to screens. I am using natural mode. Vivid mode is having too much pop.

So even I had the same thoughts when I got hands on my S10+. Was worried the screen had some issues and hence went to the Samsung store and compared with the display phones - there was no difference between what I had and the display ones. However, when I compared with my S8+ I found that S8+ display was more blue-ish than S10+. The response from Samsung was that by default Samsung had toned down the blue light in the S10 screens for improved readability.
However, I feel the colors had lesser contrast in my S10+ screen compared to my S8+ and that is a bummer - at least for me!

I have found that applying "blue light filter" and setting it's effect to minimum fixes the color saturation and reverses the washed out look on images. Another way is to go into visibility enhancements -> color adjustment -> then either apply a filter there like "Tritan" or "personalize color" and follow the steps. To me I cannot see any difference between the above steps or just simply applying "blue light filter" set to minimum. To me both look to correct the color saturation about the same.
I hope this helps you!
Hopefully they fix this soon!
Cheers ?

Hi guys. I think you might be encountering the display saturation bug.
The Galaxy S10 (USA Unlocked version in my case) has a peculiar bug in the display. When a photo is fully opened in an app such as Gallery, the photo's saturation becomes muted and cold (even with the display set to vivid and warm). It's very apparent with skin tones. I first noticed this when comparing identical photos between my S10 and S9.
If you hit the app switcher, the minimized card displays the photo with the correct saturation. Maximizing the app, causes the image to immediately turn washed out and Muted. This is appears to be a system wide bug, as it shows up in Gallery, Instagram and other places. I could not get this to show up with a screen recorder, since it's the display changing the image. I recorded it with my camera, but it appears very subtle. In person it is very obvious. I don't know how many are affected by this bug, but I'm seeing others talk about it on forums. Appears to affect all galaxy S10 models.
For a temporary fix, you can enable the blue light filter and set it to the MINIMUM setting. This will display photos in the Gallery and other apps with the correct color saturation. Hopefully Samsung will address this with a software update!

There are a lot of posts and review mentioning this problem about the camera, photos, and videos, but it's not just the output coming from the lens: it's the entire display.
It's not just that it's pinker than other devices: when you look at photos of humans or things you know were supposed to be yellower, it's noticeable and looks wrong, even without another screen to reference. Humans look especially piggy-pink. Sand looks pink. Wood looks pink.
Yes, it's possible to adjust color balance from the Settings menu, but if I adjust for reds, the whites become off-balanced: too yellow-green.
The color temperature wheel also does nothing for a separate issue: contrast and saturation. In Normal mode, it's too muted. Meanwhile, "Vivid" mode comically oversaturates. Compared to a Pixel 2 XL and Pixel 4 XL (and other screens, mobile and desktop), colors (in Normal) are more muted than expected. Parts of images that should be charteuse or neon are instead just nearly-pastel yellow-green. Darks and blacks are nearly greyish.
Can anything be done to calibrate the screen, via root, apps, or otherwise?
