I would also never connect smart TV to the internet. Years ago we purchased dumb plasma TV and set up a Linux box on older PC. The main part is Kodi (XBMC) which has addons for various online services + we have Tvheadend on another box for satelite and DVB-T2 recording. All two DVB-T2 muxes we are receiving are also sent multicast on the LAN using dvblast. Kodi can be controlled via an app on the smartphone or it's web interface. This has been working for years, some maintenance was needed but I am happy with it and don't plan changing it. This TV box is also a Kubernetes worker node for light workloads :D but that's another story.
