Here the picture again without noise. It seems that it is not due to the parameters.
Overlaying with noise brings only limited improvement.
I'll try again with a contour filter.
There's probably not enough contrast with the blue.
edit: on the last image, Colab aborted on 100 out of 125 runs. So it didn't quite finish.
