No one cares about Dolby Vision. It's an OPTIONAL standard on UHD blu-ray, one that not all display manufacturers support, and one that is not demonstrably better than the OPEN HDR10 standard (you can quibble about numbers, but I have YET to see a review with side-by-side comparisons showing the exact same material being evaluated with both formats!).
With the largest display manufactuer (Samsung) outright REJECTING Dolby Vision, the future of the format is relegated to an "enthusiast" offering, like DTS is vs. Dolby Digital. Some will SWEAR DTS is a better format than Dolby Digital...but the reality is that both are pretty equivalent and both get the job done just fine. Anyone who doesn't follow the technology (your average customer) won't care less if Dolby Vision is included or not.
