Having a better awareness of music theory definitely helps but it is by no means a silver bullet. Things can fall apart for so many more different reasons.
You can certainly appreciate music more that way, but appreciation is different from the things that you consider "good" or something you'd want to regularly engage with. Ultimately that's what matters to most.
I appreciate Coltrane from a distance. I wouldn't listen to his stuff regularly though because I do not enjoy it even after knowing what he's doing
