Perhaps you just recognize the score more easily now. I know that was the case when I saw it again in the theater after listening to the CD a bunch.
It could also be the levels sounding different on a home setup. Others have claimed that they hear the score more clearly now. Though I think it’s still too quiet.
I agree that the score differs from the CD (it always does) but I notice no change on the BD. And none quite thoroughly compared the content of the credits.
Either way, this is a good example of how useful a cam bootleg can be, though not for the credits. Maybe someone will check if you have anything specific in mind.
