Leakage of data from Smart-TV jellyfin apps?

This is maybe a little paranoid but... i have a jellyfin server that i let some family members use. one of them intends to use an app for apple tv, which i think is swiftfin or something like that. i am a bit skeptical about smart-TVs and the data they phone home with, so i was wondering if there is any chance that i could be compromised due to the linux isos i host on jellyfin due to some sneaky smart-TV stuff?
