I think there are notes and then there are notes. If the therapist is in private practice and writes "personal" notes (the interesting ones :-) those probably would not be discussed with the client, or ever be shared, could be similar to if we were keeping a therapy journal ourselves and what we wrote about our T, etc. Think of Yalom's books based on his notes? I don't think his therapy notes on people were boring?

Clinic notes or those for insurance are bound to be dull/just the "facts" because they do have others reading them so have to be understandable by all those who do.

My T and I use to joke that my notes (I saw her twice, for 9 years each time) took up an entire file cabinet drawer (along with the poems, letters, "stuff" I sent her over time). I don't think therapy in depth, over time, can have he said/she said sorts of notes like CBT/DBT sorts of therapy might as there is no "plan" or agreed-upon goal that could be discussed and which might stay constant. "Client gave therapist poem, therapist thanked client for poem and asked what it was about. . ." just does not convey it?
