Disney 4K Atmos is great, a reference quality track. It's a very slight remix (music seems to be from a better source), but it's completely seamless and faithful to the original, better fidelity than anything since the 1994 30th Anniversary Edition LaserDisc.

All DVDs (and 2010 Blu-ray) sound far worse than the 4K Blu-ray/LaserDisc and have various missing sound cues.

BFI 4K Blu-ray

BFI 4K Blu-ray has excellent master and grade, no DNR and tasteful HDR

Restored original mono mix: Toho Japan 4K Blu-ray
Unrestored original mono: 2014 BFI Blu-ray

BFI 4K Blu-ray has OG Perspecta (in 5.1 container) and a stereo downmix of it; no original mono.

The unrestored track on BFI's earlier release appears to be an almost entirely unmanipulated transfer of the original mix. It suffers from a distracting low-frequency hum. The 4K restoration comes with a restored track, which appears to be the same transfer, but which appears to be cleaned up with a moderate amount of noise reduction and some EQ, nicely opening up the high-end, and which is likely to be preferable to most listeners. All earlier releases sound poor.

Perspecta isn't a discrete surround format, instead only relying on manipulating volume and panning of the mono track across L/C/R channels, based on embedded control tones. As such, even the Perspecta track is technically just the mono mix, though the omission of the proper mono on BFI's 4K is still unfortunate.

Fox Blu-ray mono mix

As noted at Blah-Ray, the mono mix on the Fox Blu-ray, although not perfect, sounds better than the 5.1 remix and at least as good as earlier LaserDiscs, which suffer from being murky.

Kino Lorber Blu-ray 

The audio on the Kino Lorber Blu-ray comes from a better source than the various DVDs and the previous HD version on streaming. This audio is relatively untampered with, and is likely the best available source as no laserdisc was ever issued.
