I’m inclined to believe that finding a screen that’s uniform will be too much time and effort to be worth it. Others have posted in this thread that they have no orange tint/uniformity issues (side note - there is no standard test for this and it’s very subjective), so I’ve been chasing that unicorn and have gone through 5 iPhones, all with varying degrees of this issue. Either I’m incredibly unlucky, or most 13 Pro Max devices have this to some extent. One or two would be a coincidence, but 5 in a row is a larger issue.
My current 6th iPhone has a tint on the left side that is visible at night and worse with heat, but the screen looks amazing otherwise and I love everything else about the phone. I think it's time for me to exit the OLED lottery for my sanity for now
