@Star NXT bro i think its no point questioning or arguing with someone when we all know jio stb dont support Dolby Vision.. Going into the technicalities is no point when most of the ppl dont know the diff..
I think the stb does not support DV output.
I tried today in jio tv+ app in my smart tv, I am getting DV but I don't know why picture appeared blurred maybe because of low internet speed or something not sure but I got DV profiles in my picture settings
