With the curvic coupling still in place, the LP shaft is still in it's normal position. I doubt the shaft has moved back.
The ring has left the scene though, I suspect with it's blades still attached ... there seems to be little damage to the bypass guide vanes, just the fracture around the blade retainer ring transition cone ... there is little impact damage on the containment ring, and the inlet to the LP compressor looks in good shape too .. all pointing to the fan assembly leaving the scene in one piece.
