Perhaps for some people, but certainly not for me. I experience my vision like an old television set between channels, but with an extremely high pixel density (though perhaps a similar frame rate). When there's sufficient light, there's a strong bias to one color/brightness or another per pixel, although even then I can perceive the noise if I choose to. In the dark, it's all noise all the time - dark colored noise, but noise nonetheless - not to mention ghost patterns I hypothesize are due to minute transient pressure or chemical differentials. Far, far too much noise to distinguish a single photon. I've perceived this noise for as long as I can remember, back to early childhood.
