Theory 1; perhaps the files were compressed.

That would explain the noise that becomes more obvious when I increase the saturation. Sometimes, when a gradient between two colors is digitally compressed, the colors will start looking more pixelated.

Theory two; Jacobus used film scans.

It is possible that Jacobus took photos of his paintings with a film/Polaroid camera, and then recently used a scanner to create digital scans of the photographs. The distortion could be a result of film malfunctions or deterioration.
