Some movies have different 3D in different international distributions (e.g., half-finished 3D in the US theatrical version, but good 3D in the Blu-ray -or theaters- months later).
Games and operating systems/graphics drivers are constantly being updated, so some games may vary or even lose 3D, on PC the stereoscopic gaming scene works to correct/improve such situations.
