I'm unsure about the exact comparison between HDMI 2.1 and LAN cables for picture quality, but I can help with your gaming setup questions. For gaming, high-definition games often benefit from using a remote login feature instead of HDMI 2.1. Let me know if you'd like more details on that.
You cannot obtain video via Ethernet because the port is intended only for connecting the TV to the internet through tethering (as indicated on page 7 of your manual). HDMI will work instead.
Yes, Ethernet isn't sufficient. It only provides access to data streams for the "smart" functions of your device, and it doesn't transmit video signals.
