Nonexistence of colorimage merely suggests that the interpreter
version predates PostScript Language Color Extensions.  It does
not indicate anything about the hardware characteristics.

Why?  PostScript is designed to be "device independent"--you're
not supposed to CARE where your document's going.

For what it's worth, Display PostScript and Level 2 have a
"deviceinfo" operator that returns [a dictionary containing]
information about color capabilities.
