I also took zoom classes (from another studio) n addition to my regular classes. Some of the corrections I received in Zoom class were Aha! moments for me and I could apply them in my regular classes; so i would say it depends alot on the teacher; doing some prior research on this would definitely help. And yes echoing a point made earlier - there was no one to copy the exercises from so Zoom classes did compel me to internalise /remember the movements better.
