Wish I could get a retina mini with an even tint, first one had very bad light leakage, it was visible even if the backlight was on 20% in dim lighting, overall uniformity wasn't to bad though, genius looked at the photo I took and agreed to replace it on the spot.
Replacement has light leakage in the same two corners but half has bad, but has very bad uniformity, top 70% of the screen is pure bright white, bottom 30% gets more yellow and a hair darker to the bottom

. Genius took it into the back for 2mins and agreed to replace it immediately, but again, no replacements available.
Waiting for my third one to be ordered in to the store, doubt they are going to keep many replacements as it's the 128gb white cellular model.
No dead pixels or any other issues with either screens apart from the half yellow tint.
My mums 1st gen mini had an issue with light leakage, very large yellow leakage to the left.
Took it back the next day for a new replacement, the replacement was perfect, no light leakage at all and a much whiter screen.
