I have a Sony Android TV from the 2015 generation.
It always had a row to advertise random app I don't use (Netflix, Playstation Video, Disney something etc...)
It also always advertise content from those platform, you have to disable "recommendations" from apps one after one as you can only disable recommendations for an app that pushed its crap at least once.
The last update also broke hardware video decoding for a whole range of h264 videos as well as pushing some kind of weird 3rd party that seems to be something that basically monitor everything you do with your TV. It was advertised as a feature to access the TV guide.
My next TV will not be a so-called "smart" TV and not certainly not a Sony.
