I don't have direct knowledge of exactly what is different, but much of what determines how a tube functions is invisible without destroying the tube and taking the guts apart: how the grid is wound and spaced, both between its own windings and from the cathode and plate. The way audiophiles identify tubes by ribs and ridges and stuff on their plates is only that...a means of identification. The plates actually have far less to do with how a tube functions than the grid.

Can you tell by a non-destructive look that a cross-section of an EL34's grid windings are a different shape from those in a 6550 or KT88? Didn't think so. And that's a much bigger tube than a nine-pin miniature like a 7199 or 6EA8.
