Is this different per theme? Does that mean that it wouldn't pick up custom OEM
colours/settings?

The v21 suffix in the directory is for the API version in which material design
was introduced. I'm not sure yet how OEM themes modify the parent styles used
here.

See this article for the available qualifiers and how they are applied:
