After 3 weeks of a perfect screen, I now have a little white spot that is brighter then everything else. It looks like a comma "," and it's apparent on all backgrounds except a black background. A gentle rub did nothing to get it out. Rebooting and powering off are also useless. With the screen off and properly cleaned, there are no visual imperfections so this isn't a scratch but is an issue with the LCD. Does this sound like a dead pixel, or a few dead pixels adjacent to each other, to you? I guess if I can't fix it, to the Genius bar I'm bound.
