I started noticing that my week 49 i7 was developing the yellow tinge along the bottom and a little up the center. Was reading some CT/MRI's at home and noticed that some of the images weren't looking right. Then I pulled up a blank white screen and could see the tinge quite noticeable. Called AppleCare and they want me to bring it to my local Apple store to have the problem verified by a genius.

Hopefully the genius doesn't give me a hard time about this being "normal".
Usually I don't see the yellow tinge right during startup, it is after the computer has been used for an extended period of time.
