I noticed it for the first time tonight during the opening credits of Wrath of Khan. When there would be a name on screen the blackness of space wasn't so black, but when the name was off the screen it looked great.
I had a bunch of BB credits and gift cards so I went down and purchased this. Man they really need to update their software. I'm installing 32-bit Windows 7 right now in a VM to get around the poor Lion support.
