A straightforward implementation of differentiable dithering consists in applying a large support band-pass filter to the image (so that it becomes of of zero-mean), and then thresholding it at 0. Sure, you lose the property that the average colors over large regions are conserved, but the image is perfectly recognizable, even with higher contrast than the original.
