I am somewhat biased but I also think it sounds fine and if you like it then keep it. I think a lot more content will be augmented reality and volumetric within a decade so having the "TV" suffix now might future-proof your LemoTV brand.
I have my Hive posts on my holovision.tv domain through @engrave. Some of my posts have embedded YouTube videos so that's how I justify the ".tv" to myself. If I could afford the video hosting on my budget I'd probably start using Hive-Tube and rebrand holovision.tv. Again, that's my bias speaking.😁
