Doug, all ...
I realized that my post above was a bit nebulous.
My most extensive and controlled silver/copper experimentation involved the Airy-3. By experimenting with loading, I was able to close the gap between the two variants ... still preferring the copper by a small margin in the end.
Silver/Copper with the Universe was on different systems and not as well controlled. Likely, it's higher resolution expands on the differences. This would be consistent with yours and Cello's observations.
Sorry for the confusion ...
Cheers,
Thom @ Galibier
