Darktable *can* process images with brightnesses greater than 100% and can export to a number of formats which support HDR (e.g. OpenEXR, JPEG XL), but the graphical toolkit it uses...

HDR display won't happen until darktable is migrated to Gtk4, which is a huge undertaking (several person-years of effort). You can do a search for "label:gtk4" to see issues and...

Given the choice between perspective and filmic, the fact that the pipe was running in fast mode indicates you were in perspective correction.
