I know the accessibility tint setting is frowned upon because it’s likely to make your display less accurate, and people have also claimed it can reduce brightness and contrast, but I’ve achieved some pretty spectacular results using it.
I sat down last night and started playing with it, mainly to get rid of green tint, not just to make my screen cooler. First I tried the tint slider all the way to the left under the red pencil, and that made the screen a bit more red and got rid of the green tint, but it made the screen too warm. Then I tried moving the tint slider under the dark blue pencil, and that made the screen a lot cooler, but didn’t do anything to fix the green tint. Finally I tried moving the slider to the dark purple pencil, which added a bit more red to the blue, and that neutralized the green tint. Then I started comparing photos, websites, and color charts to my 2019 iMac, and I was able to really dial in the color tint slider to where my 12 Pro Max matches my iMac screen almost perfectly. Seriously, it’s almost indistinguishable. I’ve never had a phone that matched my computer screen so closely before. Here’s that setting. The intensity slider is set all the way to the left. I turned my screen this way and scrolled to make it easier to see where the tint slider is in relation to the pencils.

Now, while my Pro Max matched my iMac screen, I suspect my iMac screen has a color temperature in the 6800-7000K range, which can look a bit harsh at night, so then I wondered how it would look if I turned on Night Shift and adjusted it to match my really good iPhone X display, which is a bit warmer and probably around 6700K. Well, to my surprise, just leaving the accessibility tint settings how I had them to match my iMac and turning on Night Shift to a low level made my 12 Pro Max look almost identical to my X! Seriously, it’s so close. I watched a bunch of videos side by side and viewed pictures and webpages side by side for a while, and surprisingly, the colors of everything are pretty much indistinguishable. And contrast and brightness are still excellent too. My Pro Max still gets at least as bright as my X, if not brighter. Here’s the night shift setting I used to match my X:

I wish Apple would just provide the ability to create calibration profiles for iOS devices using colorimeters, and I still may request a couple replacements and see if I can’t get a screen that doesn’t need tweaking to look good, but I’m at least happy to know that I can make my current Pro Max screen look very good. By the way, I also ran a bunch of CPU and GPU benchmarks because I was concerned that the tint setting might add extra processing and slow something down, but it doesn’t.
