I bet that's why some of the more problematic titles (TSWLM, Goldeneye) haven't been released yet for blu. The Lowry produced UEs on DVD are hit or miss. I've started collecting the various SE discs that I know are superior to the UEs. They also have their own problems, but the colors are right and exactly what they should be. Really wish I had bought the SEs when they were originally out.

This is the best comparison I have seen of the standard def releases: http://www.bulletsnbabesdvd.com/forums/viewtopic.php?t=3053
