Absolutely. Different plastics have different natural colors. Some start out
clear, others start out white, and those are basically the only colors that can
achieve a true white (since hobby shops generally only sell white styrene, I’d
guess that it’s naturally white). Everything else will be affected by the
underlying natural color tone, much like the look of paint will be affected by
the color of the underlying coat. However, I expect economic factors were
behind the decision to use PS over ABS, and the whiter white was merely a side
effect.

Is there a simple, reliable way to discern the difference between ABS and
straight polystyrene without damaging/destroying either in the process? They
both taste the same, AFAIK...

I’ve never done a taste test on them, but polystyrene weighs less by volume, and
it has a different feel to it (it’s hard to explain in words alone, but ABS
actually seems to feel more “glossy” than polystyrene). Color spectrometry will
probably be the best harm-free way to figure it out...provided you have access
to a spectrometer (and they’re quite expensive). Beyond that, scratch tests,
burn tests, and corporate espionage might tell you what you want to know
(provided you don’t get caught attempting that last one).
