Bluray rip? What ripped it?
Was it actual bluray or some random "1080p" encode you found?
The encodes out there now only have DTS-core audio (lossy 5.1 DTS).
Just ripping the bluray right now.

Done.
The good thing is that it's a standard 7.1 channel setup (not "strange setup" or matrixed 6.1).
Making
7.1/24-bit FLAC now.
WAV looks to be 16-bit stereo downmix using Adobe.

TBH, it's a useless 7.1 mix.
It barely does anything for 5.1.
Stereo is the best option here.

As you can see, it's barely stereo.
Looks like mono just upscaled to 7.1.
Giacchino for the next two, in Dolby Atmos please.
I will not be doing a multichannel edit of this as Williams really dropped the ball on this one.
Or JJ.
Or both.
7.1 only good for the actual movie.
