Highlight recovery in a few raw converters

I found a difficult file that required a bit of highlight recovery and thought I'd show how a few raw converters handle it.  In each case, I attempted to do my best with the tools offered, but there is no guarantee I succeeded.  In DarkTable 2, I used both the highlight recovery module as well as the highlights and shadows.  The color is way off in the RawTherapee image and I assume it because I did not setup the color management in that app.  I am surprised that Canon's DPP4 doesn't do a better job with their own files.
