I agree, My own 'visual experience' of the difference is that a Sun rise is a
bit more yellow than an orange-yellow Sun set, probably for the reasons that
Alain mentioned.

The final image is beautiful. And I am amazed that you were able to re-create
most of the scene, after that computer headcrash (ouch!)

My one suggestion for this scene (for the future, of course) is that the steam
'strands' needs scattering media (or more of its effect, if you are already
using it?) The reason is that even steam like this has a 'self-shadowing'
effect, to give it visual density-- nicely modeled by scattering media with the
appropriate 'extinction' settings.  The scene as-is looks a bit like the steam
is 'overlayed' and rather uniform in its brightness/density.

Your hard work on this scene-- and your tenacity to keep at it-- has really paid
off!
