Criterion 4K Blu-ray > 2021 Carlotta France 4K Blu-ray. Carlotta has bad compression and elevated gamma levels, while Criterion shows more shadow details. See caps1 and caps2

Criterion actually handed the flawed MK2 master over to Prasad Corporation for "additional restoration" instead of working on it in-house.

Criterion 4K Blu-ray is another SDR grade inside an HDR container, with average brightness on HDR BL of 83 nits and 100-nit static DV. See fkid post

Criterion 4K Blu-ray > Carlotta, with debatable color gradings from master (yellow hues).

"Carlotta’s encodes were terrible with heavy blocking in the highlights and pervasive chroma noise. Criterion / NexSpec did much better and only occasionally struggles with skies. Grain is finely detailed and it doesn’t look filtered. Grading is debatable and particularly whether all three subsequent films (shot years apart by two cinematographers, one of them being the legendary Néstor Almendros) have roughly the same visual identity. Still, colors are adequately balanced with variations in the (yellowish) hues, there are no tints, black levels and shadow detail is excellent."

Criterion 4K Blu-ray has corrected gamma levels compared to Carlotta. See nicolas review

Encoding is clunky on both Arrow and Criterion BDs but Arrow at least included the original stereo mix in addition to the 5.1 remix, while Criterion only included the 5.1 remix.

Arrow/Kino Lorber/Carlotta all very similar

Kino Lorber 4K Blu-ray is a flawed master with degrain + regrain and bad encoding, but still better than the old Blu-ray
