Quicktime Gamma Bug
19 Included Films
The “0.88 QuickTime gamma bug” is a long-known issue where video encoded or tagged through certain QuickTime-based workflows can display too bright, washed out, and lower-contrast outside the environment it was intended for. In practice, blacks look lifted and the whole image loses density. Applying a gamma correction around 0.88 is often used as a rough fix.

Kino Lorber Blu-ray from blah-ray:
Both the Plaion and Arrow audio tracks sound like they received little/any high- or low- frequency attenuation, but the audio on the new Kino Lorber restoration is much more detailed. It's likely that it was transferred from different (superior) analogue elements. It sounds excellent.

US OOP Twilight Time Blu-ray > UK Paramount Blu-ray or US Inspired Blu-ray
The UK Blu-ray not only have some DNR applied, it's also squeezed and cropped: see comparison
The color contrast from Twilight Time is however possibly suffering the Quicktime Gamma Bug, but that's an easier issue to fix than DNR or cropped images.

MOC Blu-ray or MGM Laserdisc
Eureka MOC is far superior to Kino with also more printed booklet extras. The reconstruction work, transfer and extras date back to MGM's Laserdisc attempt. The LD master and materials were ported to the MGM DVD which in turn was paired with an updated HD master for the BDs. The film still cries out for a proper modern restoration and reconstruction attempt with the partially surviving cut sequences. The extras on LD also have PCM audio and one of the visuals in one of the cut episodes is more untouched which is censored for nudity on the modern versions. It's small but the particular element has been blurred on most versions today.
