No big surprise, since CIS doesn't have an active automatic adjustment to compensate for barometric pressure. Ya go higher, ya get less air, ya get a richer mix.

With that said, perhaps the WUR is able to compensate somewhat for altitude and pressure changes. Plenty of others here that have a boat load more in-depth knowledge on the subject matter.

If you plan to modulate between altitude extremes, then set your mixture in the middle of the two extremes. Probably not an issue to be really concerned about, though. Just consider the Mother Country and some of the elevations that Porsche's were known to run in.
