I hope you're right, but I think we'll have to wait until next season to see. I'm not convinced Burnham exists as a character yet, much less grew as one. At the beginning of the season, I couldn't tell if she was supposed to be a stoic pseudo-Vulcan, an impulsive human, a person haunted by past trauma, a well-adjusted Starfleet officer .... At the end of the season, I still had no sense of her. The climax is basically her doing another "Burnham knows best," which is exactly where we started. Other than the brief encounters with Tilly, there was precious little character work for her. Or for most of the other characters, for that matter -- the writers just moved them like chess pieces. Stamets is the most egregious example, but it's true across the board.
