I have the KS8000 TV as well, and bought it over other TVs because of the SmartThings integration.
At the moment, SmartThings appears to have more control over my 2010 Samsung Plasma TV than my brand new 2016 SUHD TV.
If I could just power it off and control very basic functions like volume and source I’d be happy for now. Has anyone written a functional device type for the KS8000 TV? Considering what this TV promised I shouldn’t have to resort to plugging it into a smart plug.
