This is the important line. While the flower was created on accident, its mechanisms proved a theory that had already been postulated. Like the Hannish theorize about it as Akasa, the Ancients first theorized about it as Dynamis, and the Elpis flowers validated their theory.

By the act of creating them, an understanding of Dynamis was gained. Hermes uses this line and the line prior to explain how they discovered it. The flowers are tangible, and are an accidental prototype for all Entelechies. By studying the accident that lead to their creation a method to manipulate Dynamis was gained.

While it is not a direct line, it is fact based on how more advanced Entelechies, namely Meteion, came to be created on purpose. Then, note the underlined, We, in Hermes' statement. He was not the only one researching the theory, and he was also not the one who achieved the accidental breakthrough.

Again. There are more Ancients than just Hermes who know and understand Dynamis. Explicitly. They just aren't named.
And neither Emet-Selch nor Hythlodaeus had ever heard of dynamis, nor entelechies. Venat had heard of it, but also admits that she knows very little about it apart from the basic concept.

Hythlodaeus assumes that the Elpis flower and the concept of dynamis had been submitted to the bureau before he joined it, but given he still had never heard of it, that means either Hythlodaeus was mistaken (and the Elpis flower was never submitted at all), or the bureau is so disorganized that such a "breakthrough" discovery was left to languish in obscurity. (My suspicion is that when dynamis was first observed, it was considered a trivial and unimportant matter, since according to the game literally no other person other than Hermes had ever managed to send a negative emotion to the Elpis flowers, until we came along. So the only colour changes noted were the different types of happiness, and any negative emotions were considered outliers and dismissed.)

Thus, the net effect is no matter how many other Ancients knew about dynamis, they were evidently forgotten, and so there is no way to contact them anyway. Which is the same result as no other Ancients knowing about dynamis that the group (Emet-Selch, Hythlodaeus, Venat) can consult about it other than Hermes. For the purposes of narrative, "only Hermes knows about dynamis" is true if the other people who know and understand dynamis (ie enough to create entelechies and influence dynamis) are all unavailable.
