They are very definitely plated.  I think them not looking plated has to do
with the lighting and the angle, and that the finish is ENIG.

Can they be either with your process?

Very much so.  Generally, whether a hole or slot is plated or non-plated
comes down to whether the data for it is in the plated drill/slot file
(often called .TXT), or the non-plated drill/slot file (often called
-NPTH.TXT).  The script can be applied to either/both.

(The exception to "generally" is Altium, which uses comments in the
excellon file with a special format to mark whether the holes/slots are
plated/non-plated.  I think this is a TERRIBLE solution).

Mitch.
