I tried them here in Portugal, so i can confirm that the problem is worldwide and not exclusive to any region.
I've always acknowledged the problem but the first 2 ipad airs that i've tried were perfect and even on bright white screens.
Now with the third one I saw just a while ago I could see a faint pink tint on the left part of the screen while on landscape mode, the difference in tint really became clear when I divided the keyboard in two.
Average joes probably wouldn't be able to tell a difference though. But if I get one like that, I will surely return it.
