One Reddit thread noted that the ads had appeared on a Sony 900F, which has a starting price of $999.99.
Unfortunately, there doesn’t appear to be many other options to get rid of the ads. Users on Reddit have reported that even if they attempt to disable “Android TV Core Services,” turn off auto-updates, and uninstall the latest update, the ads still seem to return after they restart their TVs.
If my $1000 TV started showing me ads, I'd be returning the TV.
