I’ve had double-paned windows replaced twice – once due to moisture, once to an errant baseball from a neighborhood kid.
I don’t recall them having to remove the frame, seems to me they replaced the panel in-situ but my memory could be faulty. It’s been over a decade ago.
I do remember they charged substantially more $$ for windows that had the white decorative bars between the panes, like you appear to have. The windows I had replaced had those also. 🙁
