I just spoke to Apple on the phone. I have the MBP 2.4 15 inch matte 7200rpm. It's custom made, so it came from China.
I have the yellowish tint on the bottom of the screen and I just spoke to Apple on the phone. My options were to send this computer back and receive a new one in the mail (which would take weeks), or send this machine to Apple Repair and have them replace the screen. I opted for the latter. I'm sending this computer back on Monday and I should receive it with a new screen in 5-7 business days after that.
That might be a better choice than playing roulette and hoping to get a good screen. Hopefully Apple is truly aware of the problem and has notified their repair centers with instructions to only use the non-yellow screens (be it LG or Samsung). Let us know how it goes, I'm very curious myself.
