I'll bet money that the silvery strand is tin coated, which has no effect on conductivity. They are trying to make your life easier, don't penalize them.
As far as CCA goes, if it has the right conductivity and makes a solid connection the guts of the wire don't matter.
There is even an argument that says that CCA is less susceptible to skin effect (never a real issue but just talking) than pure copper.
Always judge audio components based on performance, not whats in the box.
Audio gear is like sausage or laws, you really don't want to see how it is made.
The first example of this I saw were the original AR speakers. They looked good on the outside and they had trend-setting sound quality, but if you looked inside they were put together very haphazardly and the drivers especially the woofers looked like junk with pressed metal baskets etc.
The competitive JBL speakers looked a lot nicer inside with cast, wrinkle finish frames and neat little crossover boxes and nicely dressed wiring.
However one speaker had real bass and the other one that was the same size didn't.
