Unfortunately, the histogram in your editor only represents the image as it's currently rendered, not what the RAW file actually looks like (same as mine) This is the True RAW histogram via RawDigger (Note the green channel clipping)...

and where it's clipping...

ah, that's where I got confused. The details are obviously clipped in there, yet the histogram still has some room on the right.

There is is detail that is otherwise being lost in your screenshot. Can you you work on that area locally?

If the details weren't there to begin with, I guess it's up to the reconstruction algorithm to interpolate the data. I don't know darktable well enough to explore further, but perhaps an AI/neural-network is the way to go in terms of generating/constructing data.
