I'd say it's not as much better or worse just because it was learned to be better or worse; it's more like comparing things you know with each other.
Say you taste something with a very generic taste that you can't really describe other than 'brown with a bit of a toasty taste', then if taste something else that makes you have a much more descriptive or complicated taste and you also like that new taste, you now have something to compare against.
This has nothing to do with coffee per se or 'better vs worse', just with what you taste and if you want to explore it.
The same goes for details within a taste. A raw potato tastes different from a cooked potato, and the texture of that same cooked potato but mashed makes you experience it differently as well. If you fry that same potato, now it's different again. It doesn't really change the potato itself into something else (like changing it into a carrot or something silly like that), but it does change what you experience when eating it.
