Warner Bros 4K Blu-ray: Huge improvement in colors and detail. The restoration was done by the Academy instead of WB MPI which explains that there’s no grain management or issues with colors. They also accessed the original credit optical and scanned that one instead of recreating them digitally

Theatrical: WB 4K Blu-ray, according to Saentz, the 5.0 is a recreation of the original and subsequently 70mm mix from original elements.

Kino Lorber 4K Blu-ray is encoded in a wrong color space see post "A BT2020->P3 matrix corrects the issue (ignore tonemapping related errors)"

Arrow UK 4K Blu-ray > Paramount US and Capelight DE, same black crush on all three but the Arrow is encoded by FiM and has very good new supplements, the Capelight looks slightly low-passed, but in motion it probably looks about the same as the Paramount, see caps comparison for all three.

Arrow and Paramount basically sound the same, the Arrow has a slightly higher bitrate. Capelight is probably the same too but for now it's TBA.

Paramount US 4K Blu-ray has FEL Dolby Vision 

Arrow UK 4K Blu-ray and Capelight DE 4K Blu-ray have MEL Dolby Vision
