I don’t know if it’s still the case, but smart TVs were a bit cheaper than “dumb” TVs at one point, since the cost of the TV was subsidised by all the streaming platforms that paid to be included on the TV manufacturer’s OS, and have a customized Netflix or Amazon logo button on the remote that opens their app.

I don’t know if this is done anymore since there are hardly any dumb TVs out there being made now.
