I have actually taken to downloading 1080p versions of things I have access to in 4kHDR from Disney and Amazon. Frankly I can not stand HRD/Dolby Vision versions of things. No matter how I adjust my TV they still suffer from that ghastly soap-opera effect. To me having the background bright and in focus flattens the image making everything look like a bad set. It also makes the tiny differences in lighting of digital effects elements more noticeably.
I hate it.
They were there and they were superior to the alternatives almost out of the gate. I was working for a video game company at the time and me and the rest of the IT dept made the switch almost immediately because the results were clearly superior. Made me an advocate for them for years, probably far beyond where I should have given up. I am not sure which product cancellation finally changed my mind on them. Probably it was around the mess of Google Talk/Chat/Hangouts mess of apps.
