Germany Wicked Vision 4K Blu-ray better than US Kino Lorber?

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.

Both 88 Films and Germany Capelight are superior to the Shout! Factory in HDR10 but their FEL layer may even things out. Objectively, the Capelight looks best as they avoided the chroma blocking that’s visible in 88’s disc but they in turn included an Atmos mix. I have the Shout! Factory, love how it looks and the 4K transfer is spectacular. https://slow.pics/c/vPmFQSAH

Shout! Factory has the exclusive The Beauty of the Baud and the You Can't Stop Us All featurettes.

(caveat: "there's" in first "there's no place like home" utterance in final Kansas scene truncated)

Arrow 4K Blu-ray has stronger encode than Criterion

Encoding is clunky on both Arrow and Criterion BDs but Arrow at least included the original stereo mix in addition to the 5.1 remix, while Criterion only included the 5.1 remix.

> Disk Kino/WCL China import

review: Disk Kino

Both have better encoding than Disk Kino, some shots are better on Shout! Factory, others on Arrow

Shout Factory still has the best video while Arrow did a questionable regrade. Arrow definitely has less grain in most shots, has a worse encode and is cm v2.9 compared to Shout’s cm v4.0.

Shout! Factory/Arrow 4K Blu-ray has the original mono

The Atmos on the Sony release is reportedly better than StudioCanal's.

Disc info of the box set discs. This film have recieved multiple encode/versions in different regions over the years. The 2017 Germany4K Blu-ray is encoded differently than the 2017 Sony but not better. Also, the same can be said to 2024 France Gaumont 4K Blu-ray while comparing to the 2020 StudioCanal 4K Blu-ray. The StudioCanal 4K Blu-ray omits all the extras from previous releases, being barebones.

US Paramount Blu-ray > International WB Blu-ray

2012 US Disney Blu-ray has dubtitles. US GKIDS Blu-ray has bonuses that are absent on the US Disney Blu-ray
