It's just pulling data together from a bunch of different sources and interpreting it, talking to people, putting together case studies, presenting it in a fairly concise format, etc. Certainly other firms are capable of doing something similar but it's not as if this sort of information is readily available from a single source to just turn into a table.

What exactly are the interpretations beyond the obvious here?

For researcher and practitioners in the field? Probably not a lot. Although researchers may not have a lot of understanding about how the tech is actually being used. For the execs who are McKinsey clients or potential clients, it's probably a useful overview.
