The indistinguishability of dark events from photon responses supports this explanation because rhodopsin is at the input of the transduction chain. On the other hand, processes such as the spontaneous release of neurotransmitters cannot be completely ruled out.
So it’s like when a camera doesn’t have enough light to properly take a photo, producing a lot of grain. Like when you have a high ISO when taking a photo/video in a dark room, it looks very grainy. I guess the eye is still adjusting its “exposure” if you see some of this graininess in the dark (or when you close your eyes?)

Yes. It’s called “Eigengrau” and it happens due to the adaptation of the eye amidst the darkness.
