MacBook Pro - yellow screen issue, possible reason?

hey guys, just got my new MBP yesterday, played around with the colour settings and i reckon they made the default profile a little yellow, just so skin tones look good.

tried making some of my own profiles, and while i did make a slightly better one imo, after a few attempts, i found that most of the ones i made where the whites looked less yellow, the skin tones tended to be a little on the purple side. i don't know maybe i got a defective screen, but i doubt it it doesn't look bad or anything, it's nowhere near as noticable as the difference between tungsten light and daylight (which most people can't see)

hmm, who knows, any thoughts?
