A yellowish hue on new iPad retina display

When I just get my new iPad 4G+Wifi 64GB today, I note that new iPad screen is very warm/yellow and a distinct yellowish hue is on the retina display. It also has a whole bunch of visible dead pixels. My iPad 2 is much nicer and brighter than it. Then I take it back to Apple store and have a replace, but compared to my iPad 2, the new one still has yellow. This is absolutely disappointing.Every
