Depends on your definition of “quite pricey.” There’s no equivalent of a $250 50" Insignia FireTV, but I’ve seen Samsung signage displays on Amazon for about a $75-$100 premium over their comparable Smart TVs. They also don’t come with a stand, so if you weren’t already buying a VESA mount you’ll need to add another $40-80. There is a significant premium, but it’s not necessarily orders of magnitude.
Yes. They are sold for commercial use, e.g., McD’s menu, and are quite pricey.

And they’re made better… To be on 24x7. So you’re also paying for a better quality display. That’s worth paying for too.
