best thing i ever did with my bravia was install a custom launcher via adb to finally rid myself of the endless ads, upsetting news, and terrible suggestions constantly shoved in my face without my consent. nice to be able to uninstall the misc bloat that you can't get to with the gui and just have a simple interface. all i want is to access jellyfin and maybe one or two other apps. much better all around experience now.
here's a nice reference for a lot of the stuff installed on bravia that you can elect to remove via adb:
OMG! thank you! I was unaware this was possible. I can't stand the fact that my expensive TV came with ads built-in. I use it in "only apps mode" so at least the only ad id showed is the top third of the screen one, but not the "recommended" content tiles. I'll do this instead once I go back home
