This is very likely.

These types of noises are unfortunately very common and very hard to diagnose and fix. They come and go depending on temperature, road conditions, age/mileage, and useage. Another scenario is on very bumpy roads at high temperatures, the oil can foam, which mean you'll momentarily have no damping. No damping = clunk noise. This can happen within a single stroke if the bump is big enough.

Adaptive dampers have complex oil flow circuits, and finding/eliminating all of these types of hydraulic issues under all conditions is very difficult.
