I decided to exchange my 13 Mini as it has a pretty noticeable red tint on the right half of the display at normal brightness levels. Hoping I could just get used to it or it would improve with use, but it’s too distracting when reading white text on dark backgrounds. It’s also really obvious with anything that’s blue/purple.
I went to the Apple Store and looked at 8 other Minis and most had the same issue, maybe 1-2 were actually uniform and I couldn’t find anything wrong, but most all of them were better than mine at least so I like my chances. I also looked at some regular 13s and those were almost all worse than the Minis I looked at. Bit disappointed with Apple’s QC here.
My very first 12 Mini was quite uniform, but did have a warmer/green tint overall. I don’t mind that as much as the display having uneven uniformity, especially left to right. At least with a uniform display you can make adjustments to correct an overall tint.
