So all the stereo masterings of this new mix - the CD, the hirez (48/24) download and the stereo track on the Blu-Ray - use the same smashed (DR6) mastering.
I wanted a decent-sounding version of this new mix for my portable music player, and the Atmos mix (unsurprisingly) is not similarly affected. So I used Audiomuxer (Tools -> Audio Conversion -> tick 'Remix: To Stereo', h/t to
@sjcorne for this) to extract a 48/24 stereo FLAC from my ripped .mkv. Then I used
@HomerJAU 's Music Media Helper 8's Chapter Editor function (Open the original video .mkv, save .cue file) to generate a .cue file - moved the cue file into the same folder as the FLAC, edited the .cue file in Windows Notepad and changed the extension of the file it was pointing at from .mkv to .flac (so it was referencing the .flac I'd generated instead of the .mkv) and saved my changes. Opened the .cue file in Foobar, and voila I have the whole downmixed stereo album in 48/24 with track markers. Then I exported that from Foobar (select all, right click, pick 'Convert' chose my FLAC option) and I have individual flac files for each song.
I'm sure the downmixed Atmos isn't identical to the dedicated stereo track (truthfully I haven't listened to it all the way through, but spot checking it, it sounded pretty good) and it doesn't include the two bonus/alternate tracks, which are stereo-only on the Blu-Ray sadly, but the differences in DR are striking enough to make it worth exploring, at the very least, I think:
