It is absolutely without a doubt 100% not diverse enough.

I've spent years of my life running TPC benchmarks. They're useful guidelines, but they're simply not diverse enough to show the whole picture unless your picture is very simple. Certainly no single TPC benchmark in isolation. Maybe you can get a better idea by running all of them.

The largest gaps are around non-relational style data, JSON querying and the like. Nearly every organisation has something in that space now, and TPC-H/TPC-DS don't touch it at all.
