Or am I way off base here. My point is these formats never live up to the hype. So is the point with Dolby vision vs HDR-10
Hollywood is famous for taking short cuts and cheaping out when it comes to producing their movies. They seem to think that a logo like Dolby Atmos or DTS X is good enough for "common folks." Sort of like the Emperor's New Clothes.

The HDR situation is a bit different. Dolby Vision was created as a professional HDR format for use in Dolby Theaters. When the original 4K TVs came out there was no HDR, just the increase in resolution. So many reviewers stated that sitting in a normal living room where the TV is approx. 9 feet away - you can't see the increase in resolution. This put the future of 4K UHD in jeopardy. TV OEMs and Hollywood knew they had to do something and they did - added wide color gamut and HDR, both components of Dolby Vision. But consumer TVs are nothing like the professional laser projectors that Dolby uses for their theaters. So SMPTE and Dolby created HDR for home use.

Yes - Dolby helped create HDR10. But it is very limited when it comes to an HDR format. It is not a dynamic HDR format like Dolby Vision which can "grade" HDR on a frame-by-frame and scene-by-scene basis, something that HDR10, which is a static HDR format, can't do.

Adapting Dolby Vision for home use has not been an easy task. All the specs have to be down converted which leads to errors and such. Eventually it will be worked out. This is the problem with being an early adopter, especially when there is great pressure from the TV OEMS who want to sell the latest and greatest.

Hollywood has zero experience working with HDR other than those movies which will play in Dolby Theaters and Dolby is part of the production process when it comes to creating the end product (Digital Intermediate) which only Dolby will use in their theaters.

Of course it doesn't help that there are so many HDR formats with each being slightly different from the others.

Initially ATSC 3.0, the new broadcast format chose Hybrid Log Gamma as it's HDR format over the other formats. But now both Dolby Vision and HDR10+ are saying they too can be used, with modification, for ATSC 3.0. So instead of saying "sorry guys, you had your chance, we are sticking with HLG as our HDR format" ATSC 3.0 is now considering adding additional HDR formats. What this does is add time to the introduction of ATSC 3.0. Longer lead time means consumers have to wait.

I know that hindsight is always crystal clear but there are times when foresight and hindsight match. They are both crystal clear. I am referring to the introduction of High Definition to consumers. It was an industry wide effort with all parties on the same page. This was not the case for Ultra HD. It was and still is a "free-for-all" with no industry wide effort at all. The old expression of "too many cooks spoil the broth" applies. And who is suffering from this? Joe Consumer of course.
