You was right, that was the problem, and I can see the visualizations that I want.

See the attached image with results.

Hi Christoph,

Thanks for your suggestion, I will try that, and will tell you if it works.

I think the issue might be that the bands contain uint8 data stored as
uint16 (one extra bit seems used for GDAL's nodata) and the display
function `show_img` does not handle this. In this case casting the RGB
array to uint8 before display might work: show_img(img11a.astype('uint8'))
