I am not sure if this is client side or server side or both.
Will Plex (as a whole) will be able to detect a show/movie if it is in HDR BT2020 format (HDR 10 & Dolby Vision in the future) and able to indicate that on the client side? Using file’s metadata, like on the web client it sees “Video
4K—HEVC” but in the future would it be able to indicate “HDR” (HDR10/Dolby Vision). Same goes with other clients.
Something I have also been looking for with no real information anywhere? Anybody out there found the awnser to this question?
HDR may be possible as its a license free open standard. Dolby Vision is not and its a trademark. Support and use of it requires licensing fees to Dolby.
I am also interested in a HDR icon/tag.
my research suggest you need to look for REC/BT2100 in the metadata for the HDR colour space tag - based on this page https://en.wikipedia.org/wiki/Rec._2100 instead of the Rec2020 which is just the UHD spec - https://en.wikipedia.org/wiki/Rec._2020 also explained in the BBC paper here - http://downloads.bbc.co.uk/rd/pubs/papers/HDR/BBC_HDRTV_FAQ.pdf
So if plex can simply identify the BT2100 tag in the metadata of the file (Color primaries contains the value) then we will get the HDR tag working. this doesn’t solve dolby vision notification
but this would:
look at the following tags: SMPTE ST 2084 for PQ based HDR , SMPTE ST 2086 for HDR10, ST 2094-40 of HDR10+ and SMPTE ST 2094-10 for Dolby vision based on here: https://en.wikipedia.org/wiki/High-dynamic-range_video
