"Solaris" is considered to be the "SunOS" operating system, plus a
graphical user environment, and a few other components.

"SunOS" 4.X was BSD-based.  Sun replaced the BSD-based core of the
system with a System V derivative, creating SunOS release 5.0.  At the
same time, a new marketing name was introduced for SunOS 5.0 and it
accompanying set of components.  This name was "Solaris 2".

There is a nice table of Solaris vs. SunOS versions here:

I can't verify the correctness of *all* these release versions, but it
may help a bit.

The *real* point, however, is that there is ample precedent for calling
parts of a system with a codename that is different from the whole.

Exactly :)

Also true.
