That conclusion agrees with my impression from the non-calibrated
monitor. The lighting is deliberately strange, since I wanted to
"stress-test" the profiling, but still I tried not to use narrow
banded light sources, like fluorescent lamps. There is one
incandescent lamp and one flash bouncing off a red coloured wall paper
and diffuse white ceiling.

I understood that. I'm impressed with how well it worked. I'm not sure
exactly how white balancing works in combination with profiles, but if
I would guess I would from your description draw the conclusion that
the colour change what white balancing is adding assumes that the
profile is based on sunlight.
