Yes, but I've not tested all that many papers.  It yellowed a bit, but
slightly less than, for example, EAM, which yellows about 3 units (on 256
scale).

Museo is the only one of the tested papers that did not yellow.  But, it
faded more in the dark tones.

I think the consensus is that all papers with brighteners yellow with light
exposure.  Once the brighteners are "burned out" the yellowing stops.
Whether the brighteners have a negative effect on image permanence is an
open question in my mind.
