When it comes to Pyrrha knowing if Mercury's legs are metal, it is important to remember that she tries to use her power in a very slight manner during fights to avoid detection. Unless we assume Pyrrha automatically knows when something is metal, we have no reason to think Pyrrha is aware of Mercury's legs being prosthetic. She was specifically manipulating his boots and most directly the weapons attached to his boots, which appear to be separate. If her ability does not allow her to detect metal, then it is quite probably the case that she is clueless.
