Automatic (4K Dolby Vision)

Ultra LT 4801RW video setting.  What is the difference between Automatic (4k Dolby Vision) and the manual 4K Dolby Vision settings?  I'd like to use a setting where the player passes through whatever type of HDR data is on the content rather than forcing Dolby Vision.  Thanks.

Re: Automatic (4K Dolby Vision)

Got an answer at AVS Forum. The Automatic setting shows the Roku has detected that the display supports Dolby Vision. Advanced System Setting has an HDR Always On/Off option that controls whether Roku always sends DV.
