I think that might be a common issue with backlighting as opposed to the screen bleeding as LCD bleeding appears black (I believe). One thing you can try if it's a video issue (though it doesn't look like it) is to reset the PRAM by holding down the COMMAND+OPTION+P+R keys just as your Mac is booting. Keep holding it down for 3 chimes and then let go.
I would do a search here or at google for backlighting on MBP's as you might come up with something relating you your issue. As long as there is no obvious physical damage to the machine and it is in fact an issue with the LCD or inverter than Apple will fix it (improper backlighting like that usually is just a thing with LCD's and not really fixable and is probably only viewable when looking at the screen at an angle or during boot up). I would guess that it would be no more than a week to fix, and more likely 3-4 business days depending on their work load.
