I too previously asked the very same question. The main advantage of the CC module in my opinion is that it can be applied as multiple instances if you have mixed lighting conditions. The other big advantage is that it has spot color mapping which allows you to measure a color in one image and match that color in another image. Besides that, I feel there are times when the simplest road is the best road and in the case you present that would be legacy WB. BTW, great shot of the birds.
