The "what has changed" article on the official site a few years back broke it down exactly which shots were re-composited. I don't know if that was written with any inside knowledge or if the guy was just eyeballing it. (there seems to be a shot in Jedi that was subtly altered for some prints way back in '83, just not on the GOUT source)

I've still got the article and it does have what was recomposited. I just wonder why if they had to recomposite THOSE shots they didn't recomposite more of them.
