I have one of the earlier mid range 4k Samsungs. About two years in they gave it an update that added a Lote of bloatware, some of their own TV streaming channels full of Samsung ads. And for a bit I had Adguard home on my router and Samsung endpoints where the biggest thing blocked by far, and it was the only Samsung device in he house.
Now I have the internet disabled on it and just use an Xbox for smart stuff, will probably get an Apple TV next time they upgrade it.
I use an Xbox aswell, since my TV has an open security hole that the manufacturer refuses to patch, and because it sends unspecified data and fetches updates over an unencrypted connection.
Mind you, the Xbox does just as much snooping, but at least the Xbox fetches updates over encrypted channels and doesn't let anyone on the same network have root access to the TV's linux installation.
True with the Xbox, bat at least imo MS is slitty more trustworthy with my data than Samsung. The tv was doing more network requests than the xbox and a few Apple devices combined.
