The removal of the blue and red lights on the left side of Greedo to me say that they went in and purposely manipulated the background to put Greedo in a silhouette.
Generally overall SW 2011 is brighter but not Greedo:
no sign of any background elements.
Here's the GOUT/2004 comparison brightness maxed and contrast min'd:
The lights seem to have been painted out, and the whole right side is not recognnizable.
