I also agree with your other points, looking for DV uhd blu rays is a chore, I bought the 1st season of Westworld because I loved the show, watched it on HDR10 and enjoyed it. it wasn't until after I looked for reviews of the steelbook version and found out the discs are actually mastered in DV (what?!), which is never mentioned anywhere on the physical packaging except that big bold sign of generic "HDR", and since our up970 don't support DV yet, the consumer (like me) would never otherwise know of its superior quality unless going out of the way to look for it.
basically, the authoring software used to create UHD w/ Dolby Vision on physical media is different than straight to streaming. There was an issue on version 1.0 of the media authoring software, which led to complaints such as grey (not black) letterbox bars, such as those found on the DV-enabled UHD disc for Fate of the Furious, which is one of the first releases with Dolby Vision.
with similar issues appearing on other DV-enabled UHD media, customers took their complaints to the few manufacturers (LG, Oppo) that enabled DV from media to TV via HDMI.
People weren't seeing the same issues via streaming (VUDU has had the most prominent in releasing Dolby Vision-enabled streaming titles, Netflix the other but had their own issues with some of the DV titles, which were only found on their exclusive Netflix titles)
Dolby finally came to the conclusion that since the issue appeared from physical media and not (so much) via streaming, and the same issues weren't found on regular HDR10 titles, they looked into and found the issue with their encoding for Dolby Vision titles on disc. It has to do with how it was written to interact with the HDMI chip on-board TV's that are capable of playing Dolby Vision titles (currently few, namely LG). Dolby has passed on their fix onto the TV manufacturers, who are probably still testing the fix on all their sets, before rolling out the updates.
Once the TV manufacturers have updated the current TV's (that currently are able to play Dolby Vision-enabled media via HDMI), then we will start seeing Dolby Vision firmware enabled on more TV's and UHD players
it's the chicken-and-egg situation
as for going forward, there is also the licensing issue that may prevent manufacturers from supporting Dolby Vision. Dolby is charging a licensing fee on a part component basis. So that would cover TV (to cover streaming), probably each (DV-enabled) HDMI connection for that TV, UHD media player, as well as streaming hardware
the new HDR10+ competitor to DV is open-sourced, and only requests an annual contribution from manufacturers to support the HDR10+ spec, not on a per-component level.
Therefore manufacturers are thinking hard about the bottom line, and whether it's worth paying all of these additional licensing fees to support DV, when it sees all of these movie studios and some manufacturers coming out in support of HDR10+. To support the titles that are released as Dolby Vision-enabled from Netflix and Vudu, manufacturers may decide to only pay the minimum Dolby fee for the TV itself to support streaming, since streaming is more popular than media to the majority. Other manufacturers would rather object to Dolby's licensing scheme, and stay with support regular HDR10 via streaming and HDMI, and then support HDR10+ via streaming/hdmi in the future when there are more titles available (such as from amazon)
hope that helps
