a bit of a tangent but I'm surprised how heavily visualisers and the like always seem to focus on packing in as much colour as possible. With OLED screens it feels like there's a ton of potential for making really great black-heavy ambient visuals that so an idle TV can become a feature of a room's decor rather than just a big black rectangle in the middle of it.
Yeah, I have an older LG and it has a disappointingly simple 4k fireworks visualization when it "sleeps" that always makes me wish I could create a custom replacement.
