Here is a Samsung 65" 4K Non-Smart Hospitality Display in the US and here is the closest consumer Samsung TV also in the US.

The former is $1,023.00, the latter is $379.99.

HOWEVER, here is the Samsung commercial smart version of the first TV model.

Notice that it's actually a bit more expensive at $1080.

Also judging by figures I heard years ago for the cost to buy private information about people (well below $1 per person if I remember it correctly), I suspect Smart TV makers don't make all that much money from selling private information (especially if you consider that they're competing with the likes of Google as well as many other companies that also have massive surveillance operations) as a percentage of the total price of the TV.

I suspect that the difference in price between commercial and consumer TVs is mainly due to higher resilience in the device's design, longer and/or stricter warranties and support availability plus that they simply can extract more money from business customers (an effect you see in A LOT of things, not just this).

I suspect the current situation where non-smart consumer TVs are pretty much non-existent are a mix of big companies pursuing even small increases in profit (from selling private data) so they all inevitably end up doing that same thing that brings them a small additional revenue stream and consumers themselves being convinced that "smart" is a good thing on a TV and actually preferring those over non-smart TVs.

Certainly consumers favoring "smart" TVs would explain why even little no-brand Chinese TV manufacturers who really don't have the scale and systems for mass-surveillance are selling Smart TVs rather than non-Smart ones outside the cheapest possible TV sizes (you can find monitor-size non-smart TVs)
