The Samsung S90D (a 65" 4K model) you bought appears to sell for about $1000. Looking at Best Buy's site, you can also buy a Samsung 65" 4K TV for as little as $180 (model DU6900).
Yes, there's other differences. LED vs OLED etc. But at a glance they seem equivalent to a consumer...and one costs 5x more. The $1000 TV is targeting a market that expects more from their purchase and would potentially grate at a persistent sign-in notification. The <$200 TV is targeting a market that wants a big TV and hasn't thought much past that.
There's definitely a chance that on some models Samsung would be more aggressive about enabling smart features, because those models are expected to be subsidized by ads.
But don't think people who can afford the more expensive TV are also more tech-savvy. Some just want a nicer TV. Also, they are a much more lucrative target market than people who cannot afford the nicer TV.
It was as fascinating as it was terrifying.
It had a noticable array of sensors and (I think?) microphones along with a camera smack dab in the middle. Above that was its permanent ad display. The TV also has access to its own portal, which was what was on when I saw it. An AI-generated reporter was talking about entertainment news.
Not even Orwell could've imagined a better telescreen than this. You know it's chock full of anti-defeat protections to prevent curious minds from scoring a free TV.
