Solaris is not pure System V. I started working on the internals of
System V in 1985 and I have purchased a number of Solaris boxes in the
1990's and 2000's and while Solaris is based on the System V kernel,
it doesn't feel like System V.

I don't think that follows from the copyright headers. Those can't be
removed unless there is (essentially) *nothing* remaining of the
original.
Alternatively, you could say that, yes, it's a System V, but it's a
late 90s System V (and Solaris 10 is a 2005 System V). So it depends
on what you are after I guess: if you want to know what System V was
like in 1980-something then Solaris won't tell you that, any more than
OS X will tell you what 4.2 BSD was like. If you want to know what a
*modern* System V or BSD is like then, sure, look at Solaris or OS X.
