Unpacked my DLXLL 128 cellular silver rMini. If I was being fussy there's a SLIGHT yellow tint at the bottom, but nowhere near as annoying as the left yellow tint my air had. Not noticed any annoying gamut-gate
Will bake the screen overnight and see if it improves, but even if it doesn't, it's a keeper.
Overall, very happy.
Mine's much the same, slight yellowing at the bottom, nothing much to worry about. I wonder if it's got anything to do with positioning of the back light LEDs?
