Just watched Thor Ragnarok on 4K UHD BR on my 75” LG 4K set...absolutely fabulous. I’ve watched a few other 4KUHD BR discs I thought were not better than a good HD BR...but Thor, and Cars 3 were both amazing.
I just want James Cameron to re-do "The Abyss" in BR or HDR and add Atmos (it is only in DVD format .....or Laser Disc). The Director's cut of that movie made sense. The theatrical cut made no sense. I love that movie.

At the moment, and in my opinion (not shared by many), without an ultra-bright projector or one of the newer flat panels, HDR (not 4K) buys little, and in many cases, is not as good as SDR/WCG. In addition, I must add that my "good enough" level for video is definitely lower than it is for audio
They are worth it for me as I like the Atmos soundtracks and HDR which is more a wow factor. I don't buy very many movies.
I can also vouch for UHDs being much preferred over regular bluray. I will also say that while the increase in resolution is nice, it's not always apparent - at least not in the way that you think.
More pixels isn't as important as the quality of the pixels. When you go from 8 bit color to 10 bit color there's a significant difference. Much more depth to the picture. Like anything else (and certainly audio) once you experience it it's hard to go back. Regular bluray can look just fine, but it looks flat by comparison.
Or put another way, UHD is like good tape. 1080p bluray is OK vinyl.
