Criterion

& Pathé 4K Blu-ray have different gradings (preference). Opening scene on Criterion looks significantly worse, but similar elsewhere.

Better compression than Sony

Criterion Blu-ray > 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

For Blu-ray Criterion Demy Set > StudioCanal

Lovely underlying remaster by Criterion and Resillion but encode is sadly low-pass filtered by Pixelogic, and even then, the encode is still less than ideal. Still easily obliterates any prior disc release, but certainly wouldn't hurt to have a UK or German label take a crack at this same master.

A new 4K restoration from a 35mm nitrate print from and a 35mm composite duplicate negative.

Spain Universal Blu-ray is from a very soft DVD-era transfer; caps

Criterion 4K Blu-ray is a new transfer by UCLA, with a bit more high end detail

The earlier transfer used on the Spain Universal Blu-ray and MoC DVD is a bit boomy with boosted bass. The 1999 Criterion DVD uses an even earlier transfer with noticable artifacting and less detail.

Spain Universal Blu-ray has older MoC extra "Kent Jones and Dan Sallitt on Trouble in Paradise" with MoC watermark, and no other extras

See nicolas review: https://criterionforum.org/forum/viewtopic.php?p=841703#p841703 "The new master is simply gorgeous. Beautifully fine-grained, even the opticals don’t look that much less defined than the OCN-shots. Highlights are very nicely graded and the encode preserves them virtually flawlessly. The HDR / DV grade itself is tasteful and makes the film look tasteful. Velvety, silvery and just satisfying to look at. Furthermore, I don’t think NexSpec applied any filtering"

Twilight Time Blu-ray slightly better than Criterion 4K Blu-ray. Columbia Hi-Fi VHS probably significantly better (not been checked)

> Turbine Germany 4K Blu-ray

Turbine Germany 4K Blu-ray has a few exclusive extras

> Curzon, see caps https://slow.pics/c/mbpnweKM and see grade reference from promo images https://slow.pics/c/TfGmRNDL

Almost every source has an entirely different look. Only two that match promo images are Criterion and CG Entertainment's Italy 1080 release (for 4K they did their own HDR regrade)
