It sounds like we need to rip the new BR’s and 4k discs and apply a lut to make the 4k version match the colors of the BR. From what I’ve seen the 4k versions have crap colors unless you discover what tinkering you need. Virtually all the 4k screen caps I’ve seen look like crap. Utter crap. So washed out and unlike any film I’ve ever seen in a theater. Natalie Kalmus would be appalled.
