After commenting i looked up the actual capabilities of the port and it turns out while the port is officially only HDMI 2.0 it actually still supports 120Hz, HDR and VRR anyway. So basically it only doesn't support Display Stream Compression for 144Hz and beyond.

I quickly tested this by connecting my PC running Linux with a RX 6800 to my TV (LG C4). 120Hz, VRR and HDR were all available.

At 4K? Or are you limited to a lower resolution due to bandwidth constraints?

Yes, 4K120Hz! My TV could do 144Hz but i couldn't select it so 4K120 seems to be the limit.

Try for yourself. I get 4k120Hz when connecting my laptop directly via HDMI.
