After years with B5 and now ASP, Highlight Recovery is still useless and buggy
in most cases - at least and very obvious for the Canon EOS 7D.
I put an original RAW on my server for testing purposes which shows
intense color casts (magenta or greenish) in the sky region that cannot
be fixed by either B5 or ASP:

FWIW, the highlights of this image are by default instantly and perfectly restored
without any user interaction or HR tools with Photivo and Darktable,
both of which are well known freeware under Linux.
