Oh no, they changed the sound mix? There’s always something, isn’t there?
I don’t know why people are surprised… Sound mixes are always remixed for home cinemas on Bluray.
Maybe they retained it for the 4K version.
I don’t know why that would change anything… Films are remixed to account for the audio dynamics of a certain space. Big theatre =/= living room.
Potentially they could include all of the mixes on the larger disc, since there’s room.
