Picture Styles are proprietary to DPP. However, Photoshop came out with camera calibration models awhile back in ACR and you can edit them to make custom profiles that can really be tailored to your specs. It used to be that PS didn't do a very good job with the reds, for example, in Canon files. That issue and a few others are pretty much resolved (to my satisfaction anyway). I find that no software I've used does a perfect job in every condition, and find it's still necessary to custom-profile.
