4K encode is low-pass filtered and noticeably so, which was unfortunately par for the course with Criterion 4Ks until sometime in 2024, and the encode is still less than ideal even despite that. Still better than the Criterion and Lionsgate Blu-Ray discs for the Dolby Vision grading alone.

The UK 4K Blu-ray and Canada 4K Blu-ray both do not have the low-pass that the US 4K Blu-ray has. The UK 4K Blu-ray has some general blockiness and chroma artifacting issues, but the Canada 4K Blu-ray has at least a handful of scenes where the encode completely falls apart and massive macroblocks are visible. The Canada 4K Blu-ray also does not have hardcoded forced subtitles for the newsreel scene like the US and UK 4K Blu-rays. The grade is the same between all three discs.

The Atmos mix is the same between the US 4K Blu-ray and the UK 4K Blu-ray save for the amount of dynamic objects: the UK 4K Blu-ray has 15 to the USA's 11.
The UK 4K Blu-ray also has a DD-EX compatibility track and a lossless version of the commentary track that is in Dolby Digital on the US and Canada 4K Blu-rays.
