Yes I agree. Nothing was ever polished in service. This was meant to be 'straight out of the box' clean. I'm trying to learn how to get various effects with PBR. Figuring out how to get the correct level of shine is not as straightforward as it was with alpha and spec. PBR allows the shader to more accurately reflect light from an object. So for metal for instance, as the object moves relative to the light source, the metal changes colour as well as reflectivity and shine (pics 3 & 4 show this on the wings). First lesson with metal is that the diffuse (albedo) colour needs to be the actual colour of the metal; for aluminium this is nearly white (245,246,246). Putting less shine by darkening the smoothness channel actually shows as lighter (see wing panels) in some lights. Which makes detailing panel lines, rivets and scratches more challenging....
Next one will be duller.
