Looking back I felt my ipad 3 was too cold compared to my ipad 2, now my new ipad Air has the warmer slightly yellow cast more on left than right. I kept my ipad 2 and grew to love it, most likely going to do the same with my Air.
So yeah it is me, I am SUPER sensitive to things like sound, color, brightness... LOL. But like a said back last year, Apple could save a bunch of returns by giving us some color controls, could you imagine not having brightness control?
Everyone see's color a little different, some enjoy warm screens and some cold screens, so color controls would really be a nice addition.
But I wouldn't be so hard on some people here calling them OCD, clearly the issue is worse on some iPads. I saw one at the store that was so clearly yellow on the left you would have hard time not noticing it and enjoying your iPad.
