Not sure if it applies in your case, but with my Vic4's I'm using the same material setup, the only difference are the diffuse and bump maps.
I'm not counting a lot on the PrincipledBSDF node and its specularity, I prefer to add a second layer based on anisotropy.
But, from time to time, some bump maps, with I repeat: the same setup and the same parameters, render my character quite oily, in these case I have to increase the effect of the bump maps.
