Far from it.
The problem with smart TVs is that they provide an inferior experience to a dumb TV.
They have sluggish menu systems, are slow to switch between inputs and startup times frequently measured in 10s of seconds. Compare that to dumb TVs that switch on in less than 2 seconds and respond immediately.
Then there’s of course the ads and spying that you can avoid by not letting it on the network.
I second this. Every smart TV I've used has had an annoying "bootup" time, between 2-5 seconds, just to display the menus. Dumb TVs I've used have all displayed a menu in < 1 second.
I had the pleasure of using one in an airbnb that wouldn't allow you to change volume during the first 5 seconds. It would also not boot up on the previous input, so could be quite noisy with no recourse.
I never noticed any latency problem with my LG, I think that WebOs is quite nice. Though I really use it only for streaming, I can’t really speak about the normal TV.
