it’s an android tv based operating system made by google themselves that tailors fully to google services including gemini (in the context of smart tv, yeah it’s that confusing)
Android TV is like the parent of all tvs, boxes, sticks etc.

Corrrect, this is a rule set in the wiki too
it also points to alternative means so yeah
tbh alot of OP’s answer could have pointed to this community wiki
