Its annoying that a "smart" TV is defined as supporting an API Yahoo removed three years ago, but there are no "smart" TVs that understand their inputs and could go into some kind of sleep mode.
The "smart" booting up does take 20 seconds, but as you can see in a laptop going to sleep to wide awake should take less than a second.
Just because smart TVs are poorly designed doesn't imply there's a technical limitation to display technology. Its technically possible to make a useful smart TV, even if there are none today.
Of course, but if you are going to try and make a product which relies on well working and fast "smart" (or otherwise) TVs and there aren't any (or enough) of them today, your product isn't going to get very far.
