Description
This effect described in the spec, which makes the absorption color of the coat more "contrasty" is missing from the MaterialX implementation.
The Arnold implementation for reference looks as follows (for `coat_ior`=1.3):
| | Without | With |
| ------------- | ------------- | ------------- |
| Smooth |  |  |
| Rough |  | 
|

Research direction
The issue names no files or tests. Start with the relevant view-dependent coat absorption section of the OpenPBR spec and compare the supplied Arnold reference images for coat_ior=1.3 in smooth and rough cases, then trace the MaterialX implementation; done means the rendered results match the specified behavior in both cases.
