The monitor is mirroring the laptop.
I may be completely off base, but if a mirrored display is sharing
the same frame buffer, then full color management can only be applied
for one display target at a time. If they have different outputs then
they can possibly have different calibration curves, but without detailed
knowledge of the hardware and software or some judicious experimentation,
that isn't certain either.
So a simple explanation would be that the external display changes
because the CM is switching between targeting the built in display
and the external display when the internal one is switched off.
