Maybe I've misunderstood what you're trying to say here but, but the
daylight reflected off a *white* wall will have the same colour
temperature as the actual daylight.

Yup. But others have said that the perceived colour temperature varies
with brightness. Personally, I'm not so sure. We know that as it gets
dark, the colour temperature drops along with the brightness - although
this is far more marked on a sunny day.
