But all is not lost.
The Sony 900F has incredible "upscaling" capability that renders 1080i or 1080p content to near Bluray quality. Take a look at an "OTA" broadcast of hockey, if you can. Exceptional color, clarity and detail. So - you can be disappointed with Dolby Vision like a ga-zillion other folks or focus on the incredible picture you can get with Netflix streaming or OTA content with your Sony 900F. It's just the way it is.
To be fair, this isn't a issue with the Dolby Vision technology, nor something that Dolby Labs can control. What we have is much like what we had 15 years ago between game software developers and Hardware developers (Nvidia, ATi). The software is years ahead of the hardware needed to fully take advantage of it.
Dolby Vision is developed around a 12bit colour, 10K nit max environment, and TV manufactures are not anywhere close to those specs. We are still limited to 10 bit colour, and just now getting close to 2900 nits. Not until TV manufactures can produce products with 12 bit panels, and become fully entrenched in micro LED production (4K-10K nit) will we see the full potential of Dolby Vision.
What Sony did with Dolby Labs was to help in the development of a Software version of Dolby Vision that could be use in a firmware upgrade to current and future products. Sony did not want to go the route of LG, and Vizio by installing a Dolby Labs provided SOC.
IMO, DV and HDR10 is just a half baked product that can give you an idea of what the tech can achive, but we are just not there yet. Which is why "IMHO" don't use DV or HDR anything as a bases on buying a TV, just buy what is going to give you the best image possible for the content your going to view 90% of the time, which in most cases will not be HDR laced content.
