Is it just me, or is True Tone a negative?

Oh my gosh, thank you. I didn't know Night Shift was there too. My wife was so mad when she updated to iOS 11 that she couldn't toggle that on and off.
I agree - something I will turn off. I want a white background on my screen to to be white - not yellow if I'm in a yellow room. I also don't get this feature and how awesome it is.
Having a Note 8 I am used to, and love, it’s sRGB feature. True tone is very similar and I LOVE it as well.
See! It's awesome!
But I turn it off for movies because it does decrease color accuracy and I like my colors accurate.
Unless it's severely orange, I don't think there's a need to. True Tone colors are arguably more accurate because it makes the screen appear a more natural white in relation to the environment. Your eyes can adjust to the colors so things appear balanced regardless.
Both the colors that are being pointed to are pure gray but appear blue and yellow respectively because of your brain's ability to correct the white balance.

The thing about true tone is it's dynamic. It all depends on ambient light. There's even a situation where it will raise the Kelvin higher than the standard setting. Above 6400-6500k.
Although I wish it worked the way you're describing, it doesn't.
When you take a spectrometer and measure the screen with true tone off. It's an incredibly accurate screen. With true tone turned on it is not. It is possible to still be accurate with TT on, but the ambient light would have to be just the right temperature. Impossible to control by chance is the bottom line.

Good read

Being accurate as measured by a spectrometer doesn't translate perfectly with what our brain perceives. They can adjust themselves based on their environment and automatically correct white balance.
When I've had Night Shift on all night and turn it off suddenly, the "white" singes my retinas and appears to be a searing blue color. It doesn't look white, it looks overly blue despite being more accurate according to a measuring device. That means my eyes adjusted to the orange color, making it appear more pure white (accurate) than the proper color temp otherwise would have.
Yes our eyes adjust. But with true tone on they are adjusted to colors other than what the movie makers intended and by color space standards. Ie. sRGB DCI-P3 Rec2020 609 709 etc. That what I mean by accurate. To view content exactly the way it was designed to be viewed. In my mind it's a privilege to be able to do so. It's a great screen.

I don't find true tone useful except as a "mild night shift" option for night time. It makes everything too yellow imo, but maybe that's because I usually have dim lighting in my room. Since it depends on ambient lighting and uses a sensor/algorithms to adjust, it won't be accurate.
It's like the ambient light sensor on our devices now. Not a perfect implementation of the idea, especially in changing light conditions.

@Adelphos33, when I got my iPad Pro I pretty much did the exact same thing - turned it on, hated it at first, ended up trying it again and loved it after a little while. I’ve noticed that it makes the whites in my screen almost identical to the white bezel of my iPad no matter what lighting condition I’m in. It all just blends in and feels more cohesive. That by itself makes reading so much easier on my eyes.
I wonder if everyone’s bezel colors affect how they end up liking true tone. I can see it not being as inherently nice on a black bezeled device since you don’t have the white border right there to compare.
Anyway this is the main reason why I’m upgrading my 6s to an 8...when I go back to my iPhone the whites often look way too harsh and blue. I just wish the 8 had promotion too. It’s too bad they didn’t add that as well.

I have night shift turned on 24 hours a day, so I won't be using true tone, completely useless for me.
I agree, and I’m an amateur photographer who goes to some expense and effort to make sure my desktop display is calibrated so I can edit photographs accurately for brightness and color. I thought I would dislike true tone, but the effect is subtle and it does in fact make for a more accurate perception of color based on ambient light in my opinion. The default color for an iPad is accurate for day time, but at night the ambient light in most homes is much warmer. That makes the default appear to be too cool and too blue. Night Shift compensates for that rather crudely, while True Tone does a more accurate job. Whether True Tone cuts out enough blue light for sleep purposes is up for debate, but in total darkness it does shift to a soft and slightly warm white. When I toggle on Night Shift at the default setting th display gets much warmer. It feels nice and warm at night, but seems too orange and yellow until my eyes adjust.
Years ago I read an interesting book on color theory and editing in the LAB Color Space by Dan Margulis. He covers a lot about color perception, and how it can change based on ambient light as well as by what other colors are dominant in a scene. And of course many serious photographers use printer profiles that are calibrated by printer and also by paper, because not all paper is the same temperature of white. Some take it a step further and create different versions of a photograph to print according the color temperature of the light where the print will be displayed. Even on a calibrated display our mind can trick us into not seeing a color cast that is definitely there. That’s why we sometimes take a reference shot with a gray card (I have one that is gray, black, and white).
Anyway, I tend to notice inaccurate colors and strong color casts. True Tone is remarkably good in that I don’t notice it much. I do notice my iPad Pro is pleasant to read and view photos/video in a variety of lighting situations.

Oh good. You're a photographer so than you'll understand this. https://www.anandtech.com/show/10265/understanding-the-97-ipad-pros-true-tone-display
True tone does correct white balance but it does not make colors more accurate.
Disagree!! I didn't liked it and turned it off immediately while setting up my new Gold iPhone 8,
Night shift mode works perfectly for that.
