Radiance

Radiance 4K Blu-ray, see review

Radiance 4K Blu-ray is superior to Kino Lorber 4K Blu-ray, see mfunk9786 review:

Despite being at a considerably tighter bitrate than the Kino, the BD-66 from Radiance /Transmission is the release to own. Looks fantastic (FiM again), grain pattern is crisp, and the repeating scene error isn't on it, either. Really nice packaging that isn't as beefy as a Second Sight LE is another big plus.

Though note its different color grading from the IP-sourced but poorly compressed Fun City Editions US Blu-ray (caps)

Fun City Editions US Blu-ray

Judging from spectrograms at https://forum.blu-ray.com/showpost.php?p=23933756&postcount=57, Fun City Editions US Blu-ray appears to have marginally less filtering than Radiance 4K Blu-ray (whose padded 16-bit depth is a non-issue). There are also loudness differences, though it's unclear whether dynamic range also differs. Caveat: need to A/B both tracks to confirm, but no one has posted actual A/B impressions.

Solid upgrade and the increase in resolution works well with the 16mm source in making it appear a bit more film-like than the Blu-ray, which is obviously very good as well
