I’ve got an LG OLED65E97LA TV. It is G-Sync compatible.
I can see the G-Sync settings in nvidia-settings. G-Sync is enabled and the TV shows as G-Sync compatible, as it should be.
I enabled the Visual Indicator, but whenever I play a game, the indicator always shows “Normal”.
I’m running dual boot on this machine and if I boot into Windows 10 Pro, playing exactly the same game (i.e. Doom 2016), the indicator shows the green G-Sync text.
The TV is at the latest firmware version.

I don’t see an upload button as the pinned topic suggests, so I put it on google drive:
