Lionsgate 4K Blu-ray has terrible compression, but still beats out the old disc which was sourced from a mediocre old scan with edge enhancement, and which has compression issues of its own.

The film originally premiered with two mixes, a 5.1 for upgraded theaters, and a distinct matrixed Dolby Stereo mix for older venues. The original 5.1 mix can only be found on the earliest LD/DVD releases, as all later releases replace it with a mediocre 7.1 mix with reduced dynamic range.

The Atmos mix is based off of the previous 7.1 remix, but with futher alterations as per director's wishes. One scene intentionally drops out into silence, see this post for details.

But has more DNR than old 4K

• 4K caveat: A variety of VFX set pieces and touch-ups were added in scenes throughout the film, probably for continuity or consistency, although they might be unnecessary or revisionist. Clouds are added to clear sky of the last act.

• AI is used to fix an unwanted camera movement in one scene.

• some shots had been further stabilized, resulting in strange motion blur.

Also has missing dialog intact.
But it can be argued that the Warner Bros 4K Blu-ray 5.1 (remix) is technically a better mix.
