Is there a way to detect "fake" dynamic heads?

[Headstackk (Stacky)]

In my R6 shooter game where player can use their own avatars, I would like to blacklist dynamic heads with facial expressions (due to visibility issues) such as:

but I would like to whitelist these “fake” dynamic heads that mimic classic heads such as:

I know for the fact that the “fake” dynamic heads do not have any facial expressions (or at least they are hidden). But every one of these heads have a different MeshId despite the fact that they all look identical.

Is there a way to differentiate these heads such that I can whitelist them?

You could just run a check on the owner and the name + description of the heads, I don’t think there is any other way.
