=> Dolby Vision & open standards:

Dolby clearly weren't expecting to be blind sided and thought they would be the only "premium" option in the market place.
. Dolby Vision & HDMI Forum / SMPTE / CTA:
ST 2094-10 Dolby Vision dynamic metadata are also transferred across HDMI 2.1.
The transmission of SMPTE ST 2094 dynamic metadata (i.e. ST 2094-10 dynamic metadata of ST 2094 compliant Dolby Vision, ST 2094-20/30 dynamic metadata of Technicolor HDR or ST 2094-40 dynamic metadata of HDR 10 Plus) across HDMI is described in CTA-861-G (base document of HDMI 2.1)
. Dolby Vision & ETSI:
"Additional HDR, named HDR display management (DM) metadata, may be present at the input of the CCM system. [CCM: Compound Content Management]
The HDR DM metadata combines SMPTE ST 2086 static metadata  and SMPTE ST 2094-1/10 dynamic metadata  and , and is used to maintain the artistic intent when the content is mapped to the display capabilities."
. Dolby Vision & ATSC 3.0:
"ATSC Candidate Standard: A/341 Amendment – 2094-10
This document describes technology documented in ST 2094-10 “Dynamic Metadata for Color Volume Transform — Application #1
,” which is a technology for the use of dynamic metadata for HDR content."
. Dolby Vision & DASH-IF:
=> Dolby Vision licensing fee
A lot of people are concerned with Dolby licensing fee.
"You may hear about one other difference between Dolby Vision and HDR10. Some people will point out that TV manufacturers pay to have Dolby Vision in their displays, while HDR10 is free. While that’s true, the difference isn’t significant.
The royalty cost to add Dolby Vision ranges from less than $3 per TV to lower than $2 per TV"
TCL delivers Dolby Vision for under $600: TCL 55P605 / 55P607, best value TV of 2017 (FALD …).
Also the streaming media player Google Chromecast Ultra, compatible with Dolby Vision / HDR10 / YouTube HDR, is available only at $70, Dolby Vision "licensing fee" included.
=> Artificial HDR format war
Why contribute to create an artificial HDR format war? It won’t bring any benefit to consumers!
Facing inherently incompatible formats like Blu-ray vs HD DVD, consumers have to choose a side.
It is not the case with HDR formats.
Consumers can just require Dolby Vision TV makers or HDR10+ TV makers to just add a piece of HDR software in order to be compatible with the other HDR format. This upgraded TV will remain the same: same panel, same electronic parts, same mechanical parts!
For example, the Sony Z9D doesn’t support Dolby Vision at launch.
Sony already made the announcement - no Dolby Vision support.
Someone mentioned that Samsung's dynamic metadata HDR10 proposal passed with the competent authorities and perhaps we will see something like a dynamic HDR update on the Z in the future, but this is pure speculation.
Nobody should buy this set expecting a DV upgrade in the future - it simply ain't happening.
Then, the Sony Z9D will get Dolby Vision with a free software upgrade.
Thank you, Sony! A real consumer-oriented TV maker!
Universal HDR TV is a big plus for consumers: consumers can watch any existing HDR content they want!
