grin I think you do not do very much darkroom work. If you did you would know there are parrells in what is down in PS and what is done in the darkroom. Getting it right in camera is imporantant but refine it to excellence is a must if excellence is what you are after. Note digital is almost similar to film if you can not get it right in capture you may not be able to do too much to it afters - gross errors are unrecoverable - example blown out high lights remain blown out unless you take another frame - even raw files can only do some much.
At the end of the day it is a personal choice how much you want to DI and how real looking you want the finished to be. there is no right or wrong.
