I appreciate the learning from the experts here on how the B777 systems work and interact.
I also appreciate all who ask relevant question before speculating through more than one link in a causal chain.
Be mindful of reading post crash fan blade damage that you must consider more than what your eye sees in a single photo.
In order to cause significant fan damage due to crash impact you must have both high RPM and significant fan case crushing against the blades.
There are distinct differences to be interpreted between high RPM and low RPM ground impact fan damage as well as distinct differences between ground and an inflight damage of the fan.
I suspect that most people observing these photos would not be able to tell the difference (whether it was inflight or due to ground impact). However I do expect that the answer is already known to those at the scene, so I'll not speculate further without their comments.
