You literally can. They are called signage TVs.
Or just buying a regular TV and not connecting it to the internet. Signage TVs are specialized and will cost a lot more for a lot less.
Because nobody buys them? I have a reasonably nice 1080p60 dumb TV, and when I decide I want to upgrade, I'll be looking at 4k (or maybe 8k) signage displays. Being part of an app ecosystem at this point is a design defect on a TV, and the superior product costs more, so fewer people buy it.
I also suspect the usable life of a smart TV is a lot lower, to the point that paying twice as much for a signage TV may not equate to twice the price in the long run. Fewer parts outside the panel that can slow down or fail entirely
Because they're a specialty product sold to businesses not mass produced products sold to budget-minded consumers.
I also doubt they're technologically superior as they're just designed to display a static McDonalds menu for 18 hours a day, not play Dune in HDR at a massive bitrate. I'm no fan of tracking or similar corporate bullshit surrounding advertising but you're making a lot of (almost entirely) assumptions here about these signage displays. You'll likely be paying more than 2x the price of a comparable model considering these are likely equivalent to Black Friday TVs.
The prices are not bad on signage TVs and they sure as hell are not similar to Black Friday TVs. Black Friday TVs are known to have garbage parts. Companies are not going to put up with TVs that die quickly.
Then you will have to deal with their shitty, laggy UI. Signage TVs are not more expensive from what I have seen. They often have less features though like only 60 Hz and fewer inputs (mine only has two).
Are those signage tv have similar tech as normal tv? e.g. oled screen, low latency mode, etc?
Can't find one with an OLED screen and I doubt there are any since that would likely lead to burn in. I can't see a use case for low latency (assuming for gaming) on a signage TV so likely no. But for watching content, they work fine.
You could get an OLED monitor like the Gigabyte FO48U or the Asus PG42UQ and use it as a TV if you really wanted.
