It's honestly all the Subsurface Scatterings Fault for how it seems all doll like for some.

Mostly with how Dolls generally have form/construction/shaping that gives them a pseudo look.

So I take it as the same deal in reverse is happening here.

Everyone is basically having a Layer of shine on them. (Think of it like having some layers of clearcoat applied to your previous Mattes)

Sadly though, the skin is likely a non-starter on being reverted or adjusted. Unless they add a (who knows, how they'll even make) higher res matte, when it's mostly the extra features of the system that make it look as such.

[Least it isn't as jarring, as if they went straight into BnS Oily.]

As for scales/horns, it just is for me.

I kinda always referenced Raen and Xaela as, WhiteScales and BlackScales.

Though they tended to be more porcelain/bone offwhite, and dark blue shapped shards.

[Would be a nice surprise if the Scales/Horns had some Color choices. (yet, that's more work that we do not know if they'll consider)]

Hope you all are able to get what you desire, a toggle, a choice. or other solutions while pleasing the rest who are also happy with how it is in the images.
[or simply don't care either direction]

Least they gave us Fanta to fine tune.

But we are safe in the thoughts that they'll take feedback into account at very least.

So Keep at it.
