These are ex-SN or ex-SR A330 that LH leased until they get their own metal, and word is they use the old SN/SR cabin on these flights, but LH crew.
As they come into service in January it's not clear wether they will feature any enhanced service to make up for the loss of First Class. These A330s will be also used on the FRA-BOS flight from January.
btw: First pictures after repainting can be found here:
