And this is visible without manipulation?

Depends on how you define manipulation.

The "original" is almost black and is featureless in the dark parts.

The "manipulated" has  recovered details in the dark parts, and there be banding. Those dark parts should be easier to recover without banding. Now, maybe, those dark parts are very dark and very near to the lower limits for the camera. Then, problems is expected with any camera. But, there is not all that much noise. So ... I would say the camera has a banding problem. Maybe a banding problem most can live with.

This discussion reminds me of the discussion we had here some years ago regarding night shots. It was claimed that the Foveon cameras were bad at night shots due to noisy images. But ... the answer from some here was that it is dark in the night and therefore the images should be printed dark. And then you would not see any noise in the dark parts, as they were almost black.

Yeah ... maybe. It is often so that Foveon night shots are sharper than Bayer night shots, for some reason. Why is that?
