You can get some improvement by
1) Apply Filters -> Generic -> Dilate (grows light areas and shrinks the dithering to nothing)
2) Apply Filters -> Generic -> Erode (grows darker areas to try and get most of the original back)
3) Play with the color curves tool to get a little darker.
A 30 second demo of that: https://i.imgur.com/9U8qJoy.mp4
Wonderful. It works fine, the result is beyond my expectations.
Thank you very much rich2005
