An audio comparison would be nice Endian. The original mix should have been in 5.1 with a 2.0 matrix alternate for a 1994 film. The Atmos track is really just a 7.1 core remix that has added or spread around height channels.
I’m thinking about just waiting for the reviews on the upcoming 4kuhd disc of Leon. It should be identical but with of course massive resolution upgrades.
