You can also buy commercial dumb TV's that usually have hdmi and displayport for a little more money, at any size, and add your own smarts at will. They also last longer because they don't intentionally under build the power supplies.

When I search for non-smart, 4K TVs, the price differentials are anywhere from 2x to 10x averaging about 4x! That isn't "a little more money".
This is why I asked for links.
