I don’t know, I’ve got both and the 4k remastered blu-ray in motion looks much more filmlike to my eyes than the WOWOW release.
Sure, there might be some places where the 4k remastered blu-ray is softer than the WOWOW release but I’m sure there are places where the WOWOW release is softer than the 4k remastered blu-ray. In terms of how the two transfers feel when you’re watching them in motion, its night and day, the 4k remastered blu-ray feels like film while the WOWOW feels digital.
I personally dislike the colours of the WOWOW release as well, in particular the fleshtones, but of course everybody will have their own preference about that. I think warmer colours work better for this film.
In terms of which version to use as the source for a release between the WOWOW and 4k remastered blu-ray, regardless of what colour choices you plan to make, I think its a nobrainer, it has to be 4k remastered blu-ray, in motion it just looks more like film.
