Latest release notes now don't even refer to this issue. What's going on here? I doubt it was fixed and then not mentioned at all...
Come on Microsoft! If you really want this S and the X to compete as a reasonable home theater 4K player than you at least need to fix these simple color issues. I think you underestimate how many people buy these because of the UHD player capabilities, with the expectation that they perform to standards.
