I believe it is probably because gif is not quite as 'good'  of a format than png. (assuming that as many other variables that might be affected are the same such as file resolution, image color space, etc.)
For instance, this quote from wikipedia: "Portable Network Graphics (PNG) is a bitmapped image format that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license."

Here is a comparison from that same article:
Comparison with GIF
  • On most images, PNG can achieve greater compression than GIF (see the section on filesize, below).
  • PNG gives a much wider range of transparency options than GIF, including alpha channel transparency.
  • PNG gives a much wider range of color depths than GIF (truecolor up to 48-bit compared to 8-bit 256-color), allowing for greater color precision, smoother fades, etc.[10]
  • GIF supports animation while PNG does not (see the section on animation, above).
  • PNG images are widely supported (for instance, with modern web browsers and office software), but not as widely supported as GIF images.
