BFI

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 has excellent master and grade, no DNR and tasteful HDR

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.

BFI 4K Blu-ray is significantly better than older Blu-ray however the HDR grade is questionable as it introduces black crushes, see nic's review and caps

For Blu-rays, Germany StudioCanal Blu-ray > MoC Blu-ray see caps

All disc sourced from the 4K restoration use the same solid audio track. Older DVD releases are from a higher generation source with less detail and more hiss.

See detailed review However Criterion has better subtitles

All three are not ideal.

All three are not ideal.

• Kino Lorber 4K Blu-ray has frozen grain, sharpening, lots of debris, and handles lesser materials. The supposed non-Superscope version is false advertising. It merely reveals more picture information. 

• Criterion CAV LaserDisc is the most consistent due to a lack of image processing.
