I just purchased a New Roku Ultra which I am using on a Dolby Vision capable TV. Its SKU# is 4800R. I am assuming that this is the 2020 Roku Ultra model. I bought this to replace my 2019 model Roku Ultra after it went bad. I am aware that the major difference between my new Roku Ultra and my previous Roku Ultra is that the newer version has both Dolby Vision and HDR whereas the older version had just HDR. While testing the newer Roku Ultra, I noticed the Dolby Vision logo appearing in the Roku's main menu screen, while streaming a backlog of Olympic sport recordings in my YouTube TV DVR library, and watching some videos on YouTube. Would I be correct in assuming that the reason why the Dolby Vision logo appears in some of the videos that I am currently watching and possibly on other services that I watch in the future such as Disney Plus and HBO Max is because those videos have Dolby Vision encoded in them and my Roku Ultra is letting me know it is displaying the videos in Dolby Vision mode, or is there possibly something wrong with my Roku Ultra? This is new to me because I have never streamed with Dolby Vision before and I thought I would just ask.

Thanks.
 
dolby vision is enhanced HDR
what it means is that normal HDR has static metadata, whereas dolby vision has metadata which are dynamic to optimize each frame, it adjusts color/brightness/sharpness/tone curve/contrast when required
normal HDR should be dynamic aswell (high dynamic range) but its not dynamic at all xD

Thanks for the response. So does this mean that it is normal for my Roku Ultra to display the Dolby Vision logo on my Dolby Vision capable TV whenever I am watching something that has Dolby Vision encoded in it such as the content on YouTube, YouTube TV, Disney Plus, or HBO Max?

first google search says its normal, To get rid of it, go to Settings > TV picture settings > HDR notification
