Do you mean streambar (can the device stream video?)
I think streambar (all models) can do 4k, so a good quality 4k TV with Streambar would be a better option than a Roku TV.
Or sell the streambar and get one of the better Roku TV (TCL reviews well), and enhance sound of that with a non Roku sound bar if wanted (unsure if Roku wireless speakers can work with Roku TV or only devices).
Not having both simplifies the "which control to use" question.
Danny, I have a 5 Series TCL Roku TV, and purchased a streambar to go with my Roku Wireless speakers. Now when I'm streaming, I don't have access to Dolby Vision content. I believe this is because my streambar is now the default streaming device rather than my TV's internal Roku. Is there any way to fix this? I want to be able to use the streambar for audio but stream in Dolby Vision through my TV's internal Roku.
