Digital Noise Reduction, an image process we usually don't want in blu-ray movies because it essentially erases something important from the picture.

Kino Lorber "raw' version or VCI replacement Blu-ray
Kino Lorber "raw' version or VCI replacement Blu-ray, no comparison available
See DVDBeaver for the whole fiasco but Kino Lorber's main feature was a DNR mess but it fortunately included the "raw" version. VCI initially had a bitrate < 10 Mbps but have sent out new disc with bitrate around 35 Mbps.
UCLA has a new restoration done in 2015, but no release yet
Only VCI has optional subtitle and commentaries, while Kino Lorber doesn't

Paramount 4K Blu-ray. See caps
HDR/grading: nice, but some blown out
Encoding: inconsistent, smeared motion
DNR: inconsistent, frozen
Old Paramount Blu-ray is arguably a solid alternative choice
Paramount 4K Blu-ray mono is different version of the BD mono from the same old 2000 DVD transfer.
The 5.1 remix on the 4K Blu-ray is an appalling remix done by going wild with artificially generated stems from Park Road Post who were given the surviving mono to separate. The experience is jarring and fidelity to original mix in terms of level balance, directionality and impact is nonexistent. Not only does this sound painfully weird, but the Paramount mixers then did whatever they wanted in terms of LFE, sound pans and effect changes.
The original mono mix was not restored and still needs it badly. The 4K master is filled with frozen grain examples coming and going plus some HDR issues in addition to the usual Paramount problems. It is simultaneously better and worse than the Blu-ray master.

1988/1990 WB Hi-Fi VHS, crystal clear, albeit with some distortion in louder areas
The 4K Blu-ray reuses the same poor mastering used on the 2006 WB Blu-ray, only with a completely unnecessary bass cut and extra noise reduction.
Even putting resolution aside, the Warner Archive 4K Blu-ray has the best video. The old Blu-ray master and earlier DVD both had massive issues with colour.
That said, picture on the 4K Blu-ray isn't perfect, with strange posterized magenta glints and some instances of DNR: https://bsky.app/profile/dagscott.bsky.social/post/3leahavqi7k2l

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.

Criterion 4K Blu-ray: intact grain compared to Toho/BFI UHDs' DNR'd master
Criterion 4K Blu-ray is good, derived from the 1995 Criterion LaserDisc (which would be minimally better due to its lack of filtering) see blah-ray

US OOP Twilight Time Blu-ray > UK Paramount Blu-ray or US Inspired Blu-ray
The UK Blu-ray not only have some DNR applied, it's also squeezed and cropped: see comparison
The color contrast from Twilight Time is however possibly suffering the Quicktime Gamma Bug, but that's an easier issue to fix than DNR or cropped images.
