Similarly: Projectors don't support Dolby Vision, so I don't care about it being on a disc.Maybe it’s all a thing of the past, but my impression of Dolby Vision from reading many discussions on various displays over the last year or so is that it can be somewhat problematic.
As HDR displays continue to get brighter and, more importantly, HDR tone mapping gets better and better the “improvement” of Dolby Vision over regular HDR-10 becomes meaningless anyway.
Dolby Vision seems most relevant when looking at displays that do a poor job of tone mapping HDR-10. But tone mapping has improved significantly compared to when UHD TVs first launched.
