This is the best approach I have right now, and it only works in Filmic display mode. Unfortunately, it also affects Doll's eyes, although the difference is still noticeable. You can play with the values until it looks the way you like.
I tried this, and for some odd reason it isn't working. I'm running 3.6 and have Filmic display mode on (I'm very confused on how yours connected like that)
