loose809 is right… i have the same issue. I have close to 200 identical movies in 1080p and 4k. Color is washed out on ALL 4k movies, and not just a few. In fact, it is washed out on every device ive tried. Macbook pro via plex web, apple tv, iphone, samsung plex app, and xbox one x.
Here is an screenshot when playing via macbook using plex web. makes no difference if it is played from other devices. I think this is a plex issue and not any other devices. I have 2015 and a 2017 Samsung HDR 4K TV’s with same results. Zero problems viewing 4K media through Netflix or Amazon.
4K
1080P
