In everything I've read (see NorthU Trim, 6th Edition page 197 for
example) polars are based on TRUE wind.

Let me re-phrase the original question: Does anyone have a table that
shows for a given wind speed, what is the true and apparent wind angles
for optimum downwind and upwind VMG? (No, the polar does not contain
this information)

I agree only apparent wind makes sense.
