Paying more for fewer features doesn't make sense though. I'm also guessing the commercial displays also are tuned more for endurance and less for quality.
LG's IT line[1] is not unreasonable in terms of pricing, especially if the purchaser is also paying the electric bill, demands long-lasting color accuracy or otherwise wants a purpose-built solution. I have not used one and I don't know if budget display manufacturers like TCL and Vizio have comparable products.

Sure, but lower demand would usually mean lower price, unless the consumers are willing to pay extra for something that other products are missing. In this case, I'm not sure what the other products are missing in comparison, but I'm also not familiar with these TV's.
(or, there's benefits to having a non-"smart" tv)
