Hi-I have a new RCL 43" SMART TV with built-in Roku. Is there any advantage or need to get a Roku player, e.g., Roku Premier, Roku Ultra? When I was researching "how to buy a new TV," I believe I read that even with a Roku TV, adding a Roku player would give access to more channels. Is that correct, or am I fine with what I have? FYI, my last television was a 1986 Sony Trinitron, and I am a SMART TV, Roku novice. Thank you, JHC
