Strictly speaking, the show is somewhat based on a series of novels. There’s an awful lot of story in those that is simply not present t in the musical, but could possibly have been included in the movie. I don’t know if that’s actually what happened, but there’s certainly a canon source for substantially more content.
From what I remember reading, yes there is some added content from the books that is not in the musical stage adaptation. I think it’s more of Elphaba’s childhood (which is quite a bit in the book).
Also remember reading that one of the reasons they decided to split it was because they couldn’t find a reasonable way to move on after “Defying Gravity” (This is the big number before intermission in the musical and really does feel like the end of that chapter) to the next scene in the film, so they decided to split the films too. Not saying it was the best way to go but maybe it means they can add more book related stuff to the second half too. The musical is sorely lacking there too.
