Can you provide the original DNG so people can play with it? One think you should take into account is that modules in Darktable are applied in a certain order (bottom to top on darkroom). In particular, "Exposure" and "Base Curve" come before "Shadows and highlights". So, if Exposure pushes the info of the sky past the white point, you can not get it back later (at least that's how I understand it). Going by the histogram, it looks like this is what happening to your picture (there are a lot of pixels close to the right edge): the info was there before the exposure (and base curve) modules, but not by time you get to the shadows and highlights module.
Two tips I can give you: - check the RAW over-exposure indicator (small colors icon below and to the right of the picture in darkroom). If the area is really non-recoverable it will show as over exposed in RAW. If not, there is a way to recover it (not always easy, but the info is there) - my first step when editing complex pictures is to use the exposure and black sliders on the Exposure module to fit the data exactly inside the histogram (using the normal under/over exposure indicator). Then I know I'm working with almost all the info the file have.
