For the most part, the mono track available on the BD and UHD is fine, but there's an 8 minutes long segment which sounds terrible with artificially expanded frequency range causing very audible artifacting. The 5.1 remix doesn't have that issue. Sample

Criterion 4K Blu-ray (not by much, caps)

From cbc:

I much prefer the 4K Blu-ray track. LaserDisc has several nasty constant hums, and even after you remove that, the detail level is on-par with the 4K Blu-ray and has a lot of crackling. The 4K Blu-ray has some variable noise reduction, but it's done well and non-intrusive IMO, I watched it with that track and was happy.

Kino Lorber 4K Blu-ray is a fine release with no glaring encode issues, the new master is also fine but graded to look quite dim in HDR/DV. Unsure whether that's really respectful to the source

Old Warner Bros US release is inferior.

Criterion 4K Blu-ray > Capelight/Kino Lorber which has heavy noise reduction and opening snare hit is missing, Capelight is slightly better encoded than Kino Lorber

But still a bit overly noise-managed.

1984 CBS/Fox Hi-Fi VHS maybe better?

WB Europe 4K Blu-ray slightly better encoding than Criterion (caveat: missing Criterion extras)
