Samsung Smart TV getCurrentChannel

I use the Samsung Smart TV integration with a QLED model from 2020. On/Off, WOL and setting a specific channel all works well for me. What I am missing is the ability to report and display the currently activ TV channel.
I know that there is a function getCurrentChannel for the legacy protocol, but I have no idea whether it is true for the protocol utilized in the official integration. Anyway, that’s what I would like to see…
