Here it is at 1:1

The noise is 'best' seen in the darker areas: those that do not reflect as
many photons to the sensor. Its present in every image, but is only
obvious when the visual effect of the noise is not overwhelmed by the
number of photons hitting the sensor. So when we use high ISO, all we are
really doing is pushing the sensor and exaggerating the effect of the
random noise.

On this camera, it comes through as a gentle 'stipple' or grain like effect

here is an example from an earlier camera: Olympus E500 at 1600 ISO

Any of this make sense?
