You have to keep a couple things in mind. First, I have no idea how the image looks on your computer. There is a wide variance in rendering for machine to machine.
Second, yes, you can do just about anything in Photoshop. But that's not the point. One of the things that I emphasize in my workshops is mastering your input device, the camera, so you don't have to spend time adjusting images in Photoshop. This accelerates your workflow considerably and lets you focus on creativity instead of constantly fiddling with adjustments just to get the image you saw in your head in the first place.
Whether or not you like a particular in-camera effect isn't the issue. Knowing what's there and how to use it is.
