It isn't just the WB that you have WAY more control over.
Saturation, curves, sharpening, noise reduction, and on, and on, and on.
We do have a little disagreement here. We do agree on some stuff.
If your white balance is way off when you take a photograph, it will appear that way in post. Even if you are shooting in RAW, this can be a problem even for lightroom; been there, done it.
Yes, I am over simplifying things because the O.P. is asking about something they do not quite understand.
It also appears when people are asking questions about RAW, way to much emphasis is placed on this and many responders say that you should always shoot in RAW if your camera has the capability. This is not so. Just look at the latest cover of G.Q. It was shot in Jpeg.
There are a lot of opinions about this. A lot of pros only shoot in RAW, others in Jpeg. A lot of pros don't even use lightroom. Big deal. Whatever works for them. I am not a pro and I can use all of the help I can get.
I do use the in camera HDR feature that I have on occasion. The camera has to be in Jpeg for this feature to work. Sometimes I forget to switch back to RAW. I end up having a whole shoot mostly in Jpeg. Since I set my camera manually anyway, You know, wb, shutter speed, ISO, aperture and such, even when I am in post I don't pay attention because the photo is pretty well dead on in the first place. It has never been a problem for me; just one step that I have eliminated.
I do not use the live view or the preview buttons on my camera. Very, very rarely do I even set up a photo using the LCD screen. I prefer everything viewed through the optical viewfinder. A lot of people swear by these.
I also said that one does have a lot more control over everything in post when manipulating a RAW picture. I just kept it simple.
I am also very familiar with the Nikon D7000. I love it even though I am a Sony shooter. But I have taken many pics with this camera that I have screwed up with wb and even lightroom could not totally remedy. But I did get them close enough that most people would not even notice. If I had shot these same photos in Jpeg, I would have been totally screwed.
So yes, whatever your initial settings are whether they be in Jpeg or RAW, has everything to do with what happens in post.
The K.I.S.S. theory works very well in photography; especially when trying to explain things in layman's terms.
