Installing Xbox 360 Games Makes Them Look Better?

Installing games to the Xbox 360 hard drive may do more than just reduce load times. According to Variety's Ben Fritz, it made Lionhead's Fable 2 look prettier:
Fable 2 looks noticeably better. The graphics are sharper and brighter. So much so that it's like the game, or my graphics processor, has gotten an upgrade.

Optional game installation is one of the many features packed in the New Xbox Experience, a free software update coming November 19, though it still requires the game disc to be present in the system. A public test of the update is underway.

Shacknews has contacted Microsoft for more information on the matter.
