I can guarantee if you post this on any av forum, everyone will laugh at you.
4k and hdr are few features that you need to compare directly on TVs. You cant just use recordings or scrcaps to see the difference.

Or you could read some reviews from people who watch every quality aspect of a movie for a living.
One of if not the best 4K release so far:
http://www.blu-ray.com/movies/The-Revenant-4K-Blu-ray/147639/
Does that really sound worth the upgrade, some differences in color grading. The praise for the blu-ray review outshines it (sounds like a bigger differene to the average blu-ray than this to it's 4K release)
And in their HDR reviews it's usually praise followed by stuff that actually looks worse than on blu-ray. This is what bly-ray.com said about Mad Max: Fury road
But the combination of HDR and enhanced resolution is not an unalloyed benefit. Anyone accustomed to watching classic films on Blu-ray should be familiar with the phenomenon in which such staples as matte paintings, rear projection and painted backdrops became obvious, sometimes distractingly so, with the increased sharpness and resolution of 1080p. Something similar happens with certain visual elements in Fury Road. The most common culprit is flame, which frequently accompanies the action, whether as weapon, decoration (notably the Doof-mobile) or the outcome of some spectacular crash. If you watch the extras on the Fury Road Blu-ray, it's obvious that the film's flame effects are a combination of practical and CG, but on the UHD almost every flame looks like a painted cartoon. Just as the enhanced depth and detail are pulling you into the film's ravaged wasteland, the artificiality of these effects pushes you back out. The same is true for the fierce dust storm in which Furiosa first loses her pursuers; in its theatrical and Blu-ray presentation, the storm was convincing and credible, but on UHD one is struck by the obviousness of the computer imagery.
It will obviously get better as cameras, cgi artists and editors get better at handling 4K HDR footage. Yet blu-ray had immediate very visible benefits accross the board, even with the single layer gimped mpeg-2 versions of movies. Doesn't seem to be the case with these early upscaled 4K movies with added HDR effects.
The thing is, most movies are still filmed below 4K, processed in 2K and old movies on 35mm don't benefit much from a 4K release and don't have any HDR capabilities unless added in post processing. Which movie purists usually loath, the slight digital color grading (green tint) of Lotr EE on blu-ray got a lot of hate.
I had hoped the 4K disc format would be more future proof. Actual rec.2020 12 bit 4:4:4 Dolby vision, instead it's DCI P3 10 bit 4:2:0 HDR 10. It's better than blu-ray for sure, yet it also already feels outdated from the start. I blame the failure of HVD. 4K UHD is limited by it's max 100GB discs, that's only double a blu-ray disc, while blu-ray is over 5 times the size of a DVD.
For now there are indeed slight benefits. But sure, if you're going to pay a couple grand for a 4K HDR tv, I would want to see some 4K UHD discs on it too. I bet upscaled blu-ray will look pretty good on those new tvs as well. I'll wait for the HDR dust to settle first.
