I guess OP has a point, colored reflections *are* heavily saturated and they are less pronounced with increasing roughness of the material but when glossy, are pretty much impossible to get rid of. With the gold mtl preset, the coating with greenish absorption helps a bit but not really.
Tried to replicate the example posted above, and while it's not a 100% match, you can clearly see the strong red tint in reflections which is not as pronounced in the example. Image attached.
