Lumia 1020 :: How To Process DNG Like Default JPEG

How to edit DNG files to make them look like the default jpeg output? Is there an easy way to do this, or does this depend on the captured image?

The reason I ask is that, although I usually prefer the more natural looking images I can get from the DNG files, I have a couple of pictures where I really like the colors, saturation, etc. of the 5Mp jpeg image, but haven't been able to match a certain sparkle in the highlights or the vibrant colors of for instance the sky and water without getting an unwanted color cast or oversaturated colors elsewhere in the image.
