Sounds like drier air to me. Humidity levels can affect how new growth emerges. If there's a spell of dry air (low humidiity levels), along with heavy sunshine, leaves can dry out a bit and wrinkle as they push in growth. I've seen it here with some maples as we've moved from heavily humid weather to drier air from cold fronts. New growth can get wrinkled, especially if it's only partially out when the drier air hits.

Your plant has been moved from a relatively low altitude environment, to a high altitude one, with the attendant increase in sunlight intensity, so that may also be a factor.

This kind of thing is usually temporary and the plant will adjust.
