It’s because we’re at the limits of the human visual system. The difference in pixel pitch between 4k and 8k at the distances we watch TV is literally imperceptible.
It also doesn’t help that there’s not much content authored and distributed for higher resolutions. It’s exponentially more expensive to produce, store, and deliver.
Home Internet connections on average aren’t any better than they were ten years ago, either, at least not in the US. I doubt a lot of them can even support 8k streaming, let alone with anyone else using it at the same time.
Yeah but we’re talking diminishing returns here. Doubling the resolution to 8k makes about as much sense as doubling refresh rates to 480hz. At that point it’s going to be mostly dependent on the individual, and likely heavily subject to the placebo effect.
By my math, a 55" 8k screen has pixels that are 0.056" (56 thou) wide.
At ten feet, that subtends an angle of 0.268 degrees or 1.6 arcminutes.
There’s obviously a lot of variation and it depends on exactly what you’re measuring, but normal human visual acuity struggles to distinguish details less than about 5 arcminutes, maybe 1-2 arcminutes depending on the test.

Most of them can’t really even support 4k streaming at a bitrate that is significantly better than 1080p.
They have been saying that since 30hz and they still say that with 240hz
