Not sure what your issue is, there. It sounds like you’re just discussing whether it is the PS4 or the TV doing the upscaling (assuming you have a 1080p TV), and in your case the PS4 upscale looks poor? Even stranger that it would affect the color. Or do you have a 720p TV? I’m sure I’m pointing out the obvious, but do you have different color settings for your PS4 input? And/or do you happen to have it on ‘game mode’ to reduce input lag?

I’ve played these discs in my PS4 and don’t recall any issues. Though I’m not sure I watched through the entire film, I probably flipped through the whole thing (having been responsible for the color of it, it’s pretty much impossible for me to just start it up without scanning through the whole thing and criticizing my work. 😃 ). I haven’t noticed any issues with the PS4 upscaling 720p to 1080p or 2160p (it’s pretty sucky at DVD upscale and deinterlacing as I understand it), but I can check this disc again. PS4 is not an uncommon blu-ray player, so I feel like someone would have mentioned it already if there was a major issue.
