I've hated pretty much every animated film that Disney has released on home video because of numerous problems - digital scrubbing of grain and detail, new-fangled color interpretations - none of which were the fault of their archival team. This must have been a decision made at a high level.
With their earlier 4k release of the (shhh... 1951) Cinderella, all is forgiven, and whatever exec ruling destroyed their films, seems to have been retracted. Snow White is gorgeous!
I've not compared, but at least from memory, it also seems to have returned to, if not an earlier color palette, at least to a more accurate overall appearance. Highlights, even with HDR, are more muted, and the film has an overall less contrasty appearance, much like original prints, which one would presume were printed with the silver record.
We seem to be entering a new world of newly restored Disney animated features, and collectors of 4k UHD physical media are the immediate beneficiaries.
