Nope, screen is clean. 

I think the LCD is actually bad. Take a look at this:

That was after about 45 minutes or so? of being on. 

Just powered it down, and it seems to have the creases and if you look very carefully, the About Finder "burned in" to the screen.. With the memory etc still present. The LCD panel itself seems to be holding a residual charge which isnt normal. 

Thats definitely a bad LCD. Since this is an active matrix LCD, there are little PolySilicon transistors on each pixel. There should also be a ground plane in the panel to dissipate the charge when its not in use, etc, but its not functioning for some reason.
