Updated through USB drive, but same problem. Still get flicker with panasonic 4k blu ray player passing dolby vision through Denon 4700h to lg 77c9.

I have the same issue with a LG C9 (WebOS 5.10.04) and Denon 4700H. Playing 4K blu ray discs on a panasonic ub820 formatted in dolby vision passed through the Denon give a flashing picture every 3 seconds. When I go into the blu ray player settings and turn off the dolby vision option to give HDR10 it is corrected. Streaming dolby vision through WebOS is good though.
