BFI Blu-ray (second audio track, not included in the menu)

Criterion 4K Blu-ray or BFI 4K Blu-ray

No clear winner, Criterion SDR 4K Blu-ray has better defined grain and is cleaned-up more thoroughly. But looks grayer and flatter in daytime scenes. BFI 4K Blu-ray's HDR/DV is better in contrast but the grading can be debatable.

The subtitles of Criterion  and BFI are translated differently. See BR forum.

BFI 4K Blu-ray

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

Toho Japan 4K Blu-ray's OG Perspecta & mono (filtered but still sounds better than unfiltered 2009 Toho Blu-ray).BFI 4K Blu-ray has OG Perspecta (in 5.1 container) and stereo downmix of it; no original mono.

The way Perspecta works is it just changes volume and panning of the mono across L/C/R channels depending on embedded control tones, so realistically all mixes are just the mono, but it's still a big shame that we get a stereo (presumably a downmix of Prespecta...?) rather than than proper mono.

Criterion Blu-ray > Arrow Blu-ray > Japan Blu-ray

Both Arrow and Japan Blu-ray seem to suffer from the gamma bug so contrast is more washed out.
