When i try to convert a webp image to a PNG image doing like that: https://play.golang.org/p/yAGNTfQrx2

The converted PNG dont keep the same "contrast" as the source webp image, while it's ok when converting the webp image with:
dwebp in.webp -o out.png

The same thing occurs when i convert a WEBP to JPEG.

Im using go1.8 darwin/amd64
