Daylight covers a wide range, from dawn (2100K), through to midday

is a damn good match for daylight at the time we need to start enhancing
light levels for our own comfort at home. What we in effect do in our homes
is stretch out the early evening period before twilight for which daylight
is 2700K way into the evening/night, both at the colour temperature and
comenserate lumen level (illumination level).

Colour Temperatures out of which textbook? I've seen exteriors at 8000K
at which Colour Temperature I needed gain in the camera.

I've seen 'em higher than that. 12000 and even 15000. Of course, it doesn't
last very long.
