It looks that the vibrance is caused by the 'bleed' or bluriness of the texture. You lose some vibrance with sharpness, but you get sharpness. :) Personally, the P5 render is better. I've been noticing that the P6 Firefly renders appear more like paintings because of this bleed.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
