Like the above!
In fact, photos you open will look different in a number of ways because DPP applies your in-camera Picture Style settings as well as various other settings you may have made in your camera -- in other words, out-of-the-camera, a Raw file rendered in DPP will "look like" a jpeg would have looked.
Other Raw processors have developed their own processing fo the Raw data and often they will "go easy" on things like Contrast, Saturation and Sharpening.
If you want to experiment with this, you might start by, in DPP, setting your Picture Style to Neutral. In fact, you could go a bit farther and in your camera set your Picture Style to Neutral and then, within the picture style menu, dial your Contrast, Saturation and Sharpening all the way back to -4.
Note that this will not change the Raw data, but when you open a file with those settings in DPP what you will see will be much closer to the default "flat" preview you tend to see with Camera Raw and Lightroom.
From there, you can examine in DPP how those settings "work on" the images, play around with the different settings, and then in ACR/Lightroom play around until you are satisfied with your results.
As for sharpening, the idea is that you take control of your post-processing. And, you can create different processes and save them as presets if you'd like.
