The old DVD's track has significantly better detail compared to BD, especially on the score. The BD has some extra detail on dialogue, but also exhibits strange artifacting (e.g. sample 3, 0:20) which suggests possible AI "enhancement" or some other form of aggressive filtering. In contrast, DVD appears to be completely unfiltered and sounds good throughout. Samples

As the BD is significantly rolled off, a lot of the detail (real or fabricated) is buried in the mix and not audible during normal playback.

Puppetoon Productions Blu-ray link is 4K scan of Original Camera Negative while has some degree of DNR is still a significant upgrade over previous release

SC caps. Great-looking 4K master except for DNR'd higher-gen shots such as the opening sequence. StudioCanal resolves finer detail but has encoding issues in highlights, the non-Original Camera Negative shots and traces of chroma noise. Sony used a low-pass filter which makes the film look less sharp and finely detailed but the encode is more consistent.

Kino Lorber 4K Blu-ray is a mediocre new master, the use of the Original Camera Negative as Kino Lorber claimed is doubted and there are two brightness and color fluctuations that appear erroneous

Even though no screencap comparisons, given that Criterion is a 2K scan of Original Camera Negative, and supervised by Ken Loach, Criterion is likely the best.
