At least in the case of a Roku TV, it's the exact same Roku hardware just strapped onto the board of an off-the-shelf flat panel display. The only real difference is that the UI has selections for the TV's inputs. There's no microphone unless you use the phone app to yell at the TV or buy a different remote than the one supplied.
That's why I have a Roku TV (well that, and I like the Roku software better) versus one of the other smart TVs. I'd have a Roku anyway so this just frees up an HDMI port.
