Blu-ray

"a full frame 35 mm fine grain positive was scanned at 4K at an historically appropriate 21 frames per second. Following this, more than 160 hours of digital clean up was completed at 2K"

Eureka Blu-ray has better encode than Flicker Alley Blu-ray. Kino Lorber/BFI are older restoration and are worse.

Probably the same as the Universal 4K restoration

Given that Indicator Blu-ray is encoded by FiM and Kino Lorber uses the same transfer judging from different screenshots, Indicator is most likely to be better encoded.

Kino Lorber Blu-ray has incorrect aspect ratio for pre-2024 restorations of both silent and sound versions

Kino Lorber Blu-ray is a brand new 4K restoration from William Wyler’s personal 35mm print

> Kino Lorber, same restoration, but better encoding. The aspect ratio is slightly difference but not sure which is the correct one. See DVDBeaver

Norway Norske Filmklassikere Blu-ray see review by The Realm of Silence

• Uses the same restoration from previous Flicker Alley DVD but at 16fps

• Contains a new score based on Ole Olsen's 1893 opera Lajla , which was originally intended to be used with the film by the director George Schnéevoigt in 1929

MoC > Kino Lorber, former has correct aspect ratio (and higher bitrate and looks better/less compressed) while the latter has a squished aspect ratio, see DVDBeaver for comparison

Warner Archive Blu-ray The Jazz Singer has it included as extras on one of the DVDs
