Miles & More (Lufthansa, Austrian, Swiss, and other partners) - Proper Credit on Codeshare F vs C?

I purchased an F class ticket on UA but travelled it as the codeshare flight with a UA number on AC metal. AC does not have F (only C). My fare says F on the paper ticket on the line for this UA flight, my flight says UA, but my boarding pass says AC in J/C class.

Anyone have any experience here? Should I only expect J/C class miles (ie 250%) or the full 375% for paid F?

BTW, LH only gave me J/C miles not F.
