I just can't possibly imagine vision that has zero noise at all. That can't be physically possible. Surely people who think their vision is completely 100% noise-free are just unable to tell that it's there? Or am I just crazy? I mean this is literally the same reason why photos taken by digital cameras have noise in them...

The website just isn't accurate to what I see for some reason. It's not nearly that obvious. It's just how solid colors are constructed. I'm fairly sure that everyone has this and just doesn't notice.
But... "fairly sure" isn't completely sure. I would be so surprised if I'm wrong, but I have no idea, honestly.
There other effects like persistence of vision - staring at anything for a long time will create strange visual artefacts but I don't think that's what you're referring to.
That's... really weird. For me it's everywhere all the time, especially in darkness. I filter it out... subconsciously, or something? but not perceptually. It never distracts and never obstructs but it's never genuinely missing.
Could be caused by being autistic, I know autistic brains can be bad at filtering out stimuli.

That's indeed not what I was referring to, but I do also get this.
If I stare at something even for as short as 10 seconds, and close my eyes, some "impression" of it will stick for a few seconds. Usually just the edges or vague layout of it, and faint enough that I don't notice it unless I try to trigger it on purpose, but it's there.
And if I stay perfectly still for long enough, everything will fade to grey until I move my eyes again.
But both of these have no effects on the noise.
