I've been playing bass and guitar occasionaly (as an amateur musician) since I was 15 and I'm now in my early 30s, I studied a bit of theory when I was learning and already knew how to build chords and also have a reasonable ear, last months I decided to learn how to read sheet music and study musical theory and jazz a bit more deeper, what I found is that now I'm way more confortable with my improvisation not being repetitive and over the same scales again and again and that I have a way better knack at finding the next note on songs that I haven't heard before, so my experience is similar to yours.

As an aside, I'm pretty certain that I'm suffering from frequency ilusion, I frequently find musical theory discussions at every place that I am used to read, where in the past it seems that this things were not that prevalent.
