Does this not introduce changes in colors?? It's a way of making the histogram appear nicer, but it dos NOT improve the actual file in any way (au contraire). Blurring each channel by the same amount will give you similar results to just blurring the entire image overall. It evens out any tonal jumps that may be appearent but at the same time blurs the image. And will blurring an image improve it (in general)? Not in my book...
