That requires Emacs to know about Rich Text, and to be able to convert
that to Emacs faces.

It is similar with Word on Windows, but the names of the formats are
different.

Also, if "primary:" means this is available in the PRIMARY selection,
then we are only talking about CLIPBOARD.  Try

  M-: (gui-get-selection 'CLIPBOARD 'TARGETS) RET

instead.

no, the most useful is Rich Text, but Emacs cannot yet yank that.

On Windows, I see CSV, which I think is more useful (maybe tsvc above
is something similar).  You definitely do NOT want an image in this
case.
