I've just had a quick look at your files. At the sky condition that
you've included in the files I'd say that the sunbeam through the
window misses the sample point (therefore no direct component).
If you have the blinds down you get some reflected sunlight at
the sample point which increases the illuminance.

I have to play around with your scene a bit to confirm this but
from an initial rendering this seems to be the case.

Can't comment on the glare issue.
