I think it's worth reflecting that not every improvement initiative (in this case: see DevOps) across the whole world is moving as one large entity.
The ending line: "Otherwise in my opinion it feels more like we’re treading water and not making the advancements we could be making." sounds like an existential fallacy to me - it has been my experience that although the "DevOps vision" has not changed significantly, the actual practices and evangelism of DevOps have been infiltrating and transforming the way organizations think about software engineering.
