Horus: Prince of the Sun (1968)

4K is defective with color space issues and poor encoding, UHD replacement disc is also defective with worse encode. The UHD has visible artifacts from the bad encoding. The HDR is overdone and the Paramount 4K master has grain management.
The new Kino Blu-ray has none of the UHD's problems and is superior to the UHD in every way though it still uses the same Paramount master.

The Lionsgate BD and Paramount BD share the same lackluster HD master with DNR and image distortion. The Lionsgate is much better encoded but has a 7.1 remix which messed up the original mix design by lessening all the great Foley work in favor of the score. The Paramount BD had a 5.1 lossless version of the original mix but it's a new version where the bass has been tamed so the track has lost its punch. The Kino Lorber UHD and Blu-ray recycle this same lesser 5.1 mastering. The original mix can still be heard on LD and DVD. The 2.0 stereo on the Kino is matrixed but also does not sound as good as the 2.0 matrix audio on DVD or LD.
Kino has a replacement program for the defective UHD to fix the color space issue. The new disc is not marked, has a worse encode AND DOES NOT FIX THE COLOR SPACE! Thus it is a worse defective disc version of the original defective disc.
The Billy Zane interview on the Kino BD has technical issues in the editing and clip quality used.
