This is *stock* Google TV 4K w/ Chromecast, setup a few weeks ago. Attempting to setup the remote by going to Remotes & Accessories > Set up remote buttons > Add Device > selecting either TV, Soundbar, or AV Reciever, results in the following exception:

There was a similar post a few weeks ago that was supposed resolved by this newer version, but seeing as this WAS the version when I set it up, doesn't seem to apply here.
