This is the only reason I have a smart TV. I didn’t want one, in fact it prompted me to make an SSID and VLAN just for it, then applied a bunch of DNS blocks. Unfortunately my old 2012 TV wasn’t worth shipping across the country and the image was getting pretty dim and it had started developing dead pixels.
If you want anything above 1080p that’s a dumb TV you have to go commercial like the hospitality market and they charge you way more for it. And they won’t even sell it to you without a corporate account in most places.
The only way to get 4K and HDR without the smarts as a consumer is to buy a giant gaming monitor… and those too ask for quite a premium, because gamers.
