Question about True Lies/The Abyss audio mixes on Blu-ray

[bendermac]

maybe this was already talked about and i just missed it...

The 4K disc comes with a new atmos mix, but also has 2.0 mix. the blu-ray has a 5.1 mix. my question is: are the 2.0 and 5.1 the theatrical mixes or are they just downconverts from the atmos mix?

I'd like to know that, too, 'cause The Abyss in 70mm magnetic 6-track is the best sound mix I've ever heard. And to know it's from the analog era is amazing. The NTIs must have been involved in this as no mere mortal could have come up with what I heard that day of July 2019 in the theater.
