IP Cameras Wasting Power Using PoE?

In class, we had a comment:

"I've had cameras that are not capable of speaking LLDP which, among other things, means that when the switch feeds the device PoE they will be over allocating/wasting power because the device cant tell the switch how much it actually needs. Seems like a logical concern from the IT teams, yet I don't hear much discussion on this topic from vendors."

Any experiences like this or thoughts here?
