Not sure what you mean. To convert a bunch of photons into electrons and then into something your eyes can assimilate as a picture requires a fair bit of wizardry in any case. A camera can take you so far, with pre-sets for sharpening, saturation, contrast and the rest, along with focus, shutter speed and ISO etc, but judging the result on a tiny screen won't allow you to see some errors.
The aim is always to produce the best final image of which you are capable. And this will be using a decent screen in conjunction with post-production skills. Learning to use a camera is just one part of photography. Learning PP is essential if you want the best results.
I'm shooting a lot of show jumping at the moment, which is pretty tricky, and as it's mostly for immediate printing there is little time for any post work. So it has to be as good as I am capable of making it, or I starve. But this doesn't mean that pretty much all of the shots couldn't be improved if there was time for leisured editing. Pretty much any shot can be improved in post, just as pretty much any shot can be improved by using a better lens. When shooting jumpers I add extra in-camera settings that I don't use when I know I have time to edit. In other words, I set the camera according to the job in hand.
The mistake is thinking that lazy shooting can be fixed with software, either in camera or in post. Without software there can be no digital photography (and without chemistry there can be no analogue photography - same principal).
The wider your skill set, the better your photography will be. In camera PP is one of many tools you need to learn to use if you want to become a decent snapper.
If you get satisfaction from your photography without any post production, fine.
But you'll end up with better pictures if you learn to edit.
