West Indies: The Fugitive Slaves of Liberty (1979)

Arrow 4K Blu-ray is encoded by FiM and 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.

Arrow and Criterion 4K Blu-rays have differing extras 

Criterion has FEL Dolby Vision, Arrow has MEL

Arrow Limited Edition includes the Theatrical Cut Blu-ray from an older HD master, most likely from a 2K scan of an interpositive.

The mono on the Criterion is severely filtered resulting in it sounding incredibly muffled. It is nearly as filtered as the 2003 original Universal DVD which had extreme filtering and sounds horribly thin. The 2008 DVD remaster and original Laserdisc analog mastering are mostly left alone. The original LD master is from a worn element but otherwise sounds very natural. The 2008 DVD is the highest quality version we have without the heavy filtering and the defects of the LD master. It isn't perfect but easily the best of the main four sources by a dramatic margin. 

The existing 4K SDR restoration looks excellent, but the Criterion extras are limited and disappointing. The classic Stewart interview commentary from the LD is ported over but given a new mastering. Compared to past releases it has been very slightly noise reduced.

Wonderful underlying remaster by Criterion and Resillion, but NexSpec encode has clipped highlights with the occasional blockiness. The Criterion Blu-Ray, sourced from their 4K remaster, ironically makes for a more consistent and overall pleasing experience.
