No TV allowed in our house (it's unrelated to ads: they didn't exist on TVs back when we decided to outlaw TVs at home).
I'm using something which is arguably both cheaper, bigger and gives more of a "cinema" feeling: a 1080p projector.
4K projector can be pricey, but there are a huge lot of very reasonably priced 1080p projectors. Just make sure to find one which is compatible with the size of your room (mine is in a big living room, so the smaller models weren't fit).
It's hooked to the system ceiling. If you don't like that look you can put them in a trap that comes down or use one of the newer, fancier, "short throw" ones.
The diagonal I have (for a few hundred bucks: 400 EUR IIRC) is something silly like about 350cm/138inches. Movies, sports, video streaming (Youtube or similar), ...
In my case it's the best solution: I love the theater feeling a projector gives and I definitely and positively hate the sharp and crisp pictures all these new TVs do give. Every time I see one at a friend I simply cannot stand the experience. And inversely: when friends come at home they're always impressed by how good the picture is from my cheap 1080p projector. I didn't even bother with the wall: I just project the picture on a regular blank wall. I didn't even make the wall perfectly flat: I just painted it white myself (and not even with a projector-specific paint: I had no idea these existed when I painted the wall).
It's getting used everyday since two years (had a 720p before that) and lamp use ain't even a concern.
As a bonus it's still trivial to find projectors without microphone listening to you 24/7 and which aren't sniffing on the HDMI ports.
Now I don't doubt that in the future we'll be graced with no other choice but "smart AI projectors", but that day hasn't arrived yet.
