Is there any chance that the Vader No and the Krayt dragon scream sound better on the final blu ray? They just didn't sound integrated into the scene. Perhaps the youtube video that was leaked wasn't what the final product would sound like? I could tolerate those changes begrudgingly if they didn't sound so awful.

No, they still sound awful. They just don't sound like they belong there, especially the Vader No.. It's too prominent in the mix and doesn't blend in very well.
