You can adjust the sharpness and saturation using the DPP software that came with your camera if you shoot in RAW. Sharpening and saturation are applied in-camera to generate the JPG files. As such, some information is altered/lost in the process that cannot be recovered from the JPG file. The higher settings, the more you alter/loose. If you apply sharpening and saturation during post processing then you have complete control and can apply as much or as little as appropriate on a per picture basis.

Comparing P&S vs DLSR setting for sharpness and saturation is analogous to comparing TV settings from the showroom vs settings after a proper calibration. Most people complain that a calibrated TV looks soft, dim and under-saturated because they got use to the eyeball searing settings out of the box.
