Onkyo Receiver LG TV HDR mode


I have an Onkyo receiver connected to an LG OLED tv and I’m trying to find if the TV is in HDR mode. I have used the onkyo comand ‘onkyo video-information=query’ which brings back a lot of info on the video resolution, refresh rate and colour depth etc. both into and out of the receiver but it doesn’t tell me if it is HDR. Is there a way to find out from either the onkyo or direct from the TV to see if the screen is in HDR Mode (even better if it can tell me which type HDR10 Dolby Vision etc)?

Many thanks
