FWIW, mine looked kind of bad out of the box with a black screen but 4 months later the backlight bleed is gone. I have the floating apple logo with black background as a screen saver and I can't see any backlight bleed when I walk into the room with the lights off.
Totally unrelated to the subject.
But for a modern display (like LCD) you shouldn't have a screensaver instead of simply shutting down the display. It just use the display for nothing really.
