Arrow 4K Blu-ray

Arrow 4K Blu-ray is encoded by FiM encode is better than Criterion, see caps https://slow.pics/c/Z2RRQAAT

Criterion 4K Blu-ray vs Blu-ray: caps colors are more different and nuanced than anticipated even in the SDR-converted caps and the usual gain in highlight detail is also apparent. Encode looks excellent except for the brightest areas as usual.

5.1/5.0 mix (essentially a 4-track mix in 5.1 and 5.0 containers respectively)-Arrow/Criterion 4K Blu-ray. Only imperceptible differences in bit-depth: 20 vs 24.

UK ICON 4K Blu-ray

UK ICON 4K Blu-ray (caps)

UK 4K Blu-ray has a slightly better encode than US Shout! Factory 4K Blu-ray and Germany StudioCanal 4K Blu-ray

5.1 mix is flawed on Shout! Factory/ICON, a phasey upmix instead of the proper discrete surround. The UHD 2.0 tracks are downmixes of that track.
2008 Fox Blu-ray sounds great, very close to the original 70mm mix, only with split surround.
2001 DVD has the original mix as 4.1 and matrixed 2.0.

Imprint 4K has a 4.0 track. The StudioCanal 4K Blu-ray has a different 5.1, unclear if it's the same as Fox BD.
