Well I sure do, sorry!!
I guarantee it's the kind of screen used despite the buzz floating around the net that it's some super secret color warmth setting imposed by apple in different build numbers.
I completely think this is a valid reason! I do laptops and get repair requests all the time for slightly off kilter screens. A company is selling a specific product, and if the parts change without us knowing consumers reserve the right to be compensated or request replacement. Hell some people that come in here PREFER the old crappy macbook screens as opposed to the amazing new one we can put in the for CHEAPER. That's their right.
