Another thing I noticed while showing a friend the difference between the Han/Greedo shooting first scene - in the SE version everything is far too dark. Yes, you can see Greedo, but you can't see anything in the background. In the original version you can see the textures on the walls etc.
Somewhere (X0 project?) I read about this being like the visual equivalent of turning the bass and treble controls up to maximum because it "sounds better". (Which it doesn't of course.)
