I have a Samsung UBD-K8500 4K bluray player connected to my TCL 55R615 with an amazon basics HDMI 2.0 cable. Both have the newest software version. Playing The Matrix 4K bluray and the Grease 4K bluray, both encoded with Dolby Vision, only the "HDR" icon pops up in the corner. In the TCL picture settings I have the option of turning on or off the "HDR and Dolby Vision icons." From that I assumed that there are separate icons for each version of HDR. Is there a certain configuration of the settings on either device I need? (I've tried tons of different settings) Or is there actually only an "HDR" icon that serves both HDR10 and Dolby Vision?
