All wood recovers when returned to it's original moisture content.

********!

Dry some green oak and then try and get it back to its original shape -
not going to happen no matter how wet you get it.

Oak in particular behaves very differently depending on how it was
seasoned. Kiln dried stuff be less likely to distort in high humidity
than naturally dried stuff.

Engineered or otherwise.

The point is more about the speed of absorption in both types in this case.

The direction of the bend in the OPs case would suggest it was the ply
swelling that was causing most of the movement.

Perhaps I was inaccurately calling it engineered oak. In fact it is
made of small blocks compressed and glued together and is the same both
sides. Is that better or worse.
