Does learning how to drive a stick shift make you a better driver? If it does, probably only minimally. It does cause you to learn how the engine's power band and gear ratios work together though. Doesn't mean you can't still drive an automatic, or that someone who only drives automatics and barely thinks about engine power band and gear ratios is automatically a worse driver. Just different techniques to a similar purpose.
Jazz will make you learn more skill and theory without taking anything away from your current style. Undoubtedly, it will teach you things that can help you better understand and appreciate what you currently play, maybe even motivate you to take a newer and more creative approach to your current repertoire. Not getting it down won't hurt all the progress you've made to this point, or prevent you from further progress.
