Yes, the reduced mileage / increase in part cah fares is Club Europe only.
No reductions (yet) for WT+, Club World or FIRST.
The golden rule with AIRMILES is to keep checking their site, as things change.... as Roger comments above, some fares book in to revenue fare buckets and will score TP's and miles back.
Redemption classes are U (CE/CW) and X (Traveller) and score 0/0
