ITS NOT THE DISPLAY ITS THE LED'S
Can't you guys read. This happened last year, same exact comments, same exact OCD complaints, etc.
"The most common commercially available White/Warmwhite LED is made by mixing the blue light from a GaN chip and the yellow light from the emission of a yttrium aluminum garnet cerium (YAG:Ce) yellow phosphor coating. "
"White LED's" are actually blue LED's that have yellow sulfur/gel/etc on top of them. when they are first used they will be warmer "lower kelvin".. As they are used they will eventually reach whatever kelvin score the bin number they came from.
My LED Vaio laptop was slightly yellow now its pure white/yellow
My LED 23" display same thing
Here is a post from an electronics forum

if you overpower a white LED this will essentially do what a normal white LED does but in a small time frame. white LED + overload it = Blue LED
Are you 100% sure that this yellow screen will get cooler as time goes by?
