I realize that your eyes adjust somewhat to the screen as you use it and differences are mainly picked up when one screen is compared to another, but it seems to me that the screens on my iPad Air and rMini have improved with use. I considered both to be good screens when I originally purchased them but the slight dinginess or warmness on the left side of the Air has lessened and the screen looks brighter overall. The rMini was slightly warmer at the bottom and that is no longer noticeable either. The other weird thing is that the past few days the screen on the Air was not as bright as my mini or iPad 4 even at 100% brightness when previously it was as bright if not brighter. Now it is back to being slightly brighter than the iPad 4 and rMini. Has anyone else noticed changes on the new screens?
