I think you may be misremembering. A researcher does come running to him when the lykaons (muscle-wolves) become violent, but not to ask for his aid, but rather just to let their superior know about the situation; this same researcher lets Hermes know that their colleague will unmake the creatures:
I had just fed them myself, and the okyupetes were keeping a wide berth. It is the nature of the lykaon that is to blame. Their innate viciousness.Unsolicited, Hermes interjects himself into the situation because of his distressed feelings about the deaths of these creatures.
Temperament aside, it is an outstanding creation, perfect in form and function.
Though it may not be suited for release, I've no doubt that the bureau will accept its concept for preservation.
In any case, there's no point in postponing the inevitable. Doros will revert them all once the paperwork is in order.

If I'm trying to be objective, I don't think this provides us with enough information to move the needle one way or the other. As you mentioned, Ktisis Hyperboreia weakens his opponents, and since we don't know by how much we can't learn much about Hermes' strength from that.
To put it in mathematical terms, what we learn is the inequality:(EMET + WOL + VENAT)/HYPERBOREIA > HERMESSince HYPERBOREIA could be any value between 1 and infinity, it doesn't get us any closer to understanding the value of HERMES.
