Let's put this in perspective though. The negatives were digitally mastered in 1993, using the best available technology. The negatives were cleaned and fully restored to their best abilities, before the changes done in 1997 and 2004; when as has been repeadidly explained - new effects shots began to take the place of parts of the original negative. I'm prepared to believe the quality of that master may well be better then the quality they could pull from release prints - or other generational copies, unless they are willing to invest a lof of money into the restoration.
