I am pretty sure LH will provide evidence to UA that you were upgraded and then downgraded with a compensation. Therefore LH used your GPU to "pay" the compensation.
Legally it's attempted fraud to ask for both.
Attempted fraud? You're a bit over-dramatic.
OP should get both the compensation and the returned GPU. OP would get both the compensation and the GPU returned if this were a UA flight. OP should contact UA to get the GPU returned.
