I have an LG OLED and I just use HDMI CEC (HDMI control) to power the TV on/off. The way I set it up was to program the DVR remotes master power and volume to the AVR and use HDMI CEC to turn on the TV and DVR. Works great. One button on, one button off. You aren't going to be able to control the TV apps with it if that's what you're getting at. More @Wikipedia
