Are you using some Retina display model? Then, which Emacs are
you using on OS X?
The NS port, which is bundled with the standard Emacs
distribution, always displays images with magnification and
interpolation because of lack of high-resolution image display
support. As a result, all the images look blurry compared with
the surrounding text on a Retina display.
The Mac port, which is distributed separately from the standard
distribution, has high-resolution image display support. Also,
it modifies DocView mode so it asks external programs such as
ghostscript to generate large images for high-resolution
environments.

If you want to try the Mac port, there's a precompiled binary
package: https://github.com/railwaycat/homebrew-emacsmacport/releases
