Color management tends to be an error prone issue. Even if you think everything is setup correctly, you might haven just fallen into a pit. In your specific case, are you sure that the vcgt of your monitor profile was correctly loaded into the display driver? Any color managed software - including darktable - can only take care of the color rendering part. The adaptation of monitor gamma is in the duty of your display driver. If it fails you are working on a wrong monitor gamma and all images are displayed too bright or too dark. Argyllcms comes with a handy tool called dispwin. With option -V you can check if the loaded vcgt fits to the one in your monitor profile. Any discrepancy means that something went wrong.
