Sorry, I just found the answer to the below on the LH website. Kept original question intact and added answer below in case it assists someone else.
We used e-vouchers to upgrade intra-EU flights. We just checked in and while we're seated in business class seats, our boarding pass says "Eco Classic" for the Class.
Will we have lounge access and a free baggage allowance without regard to status?
It seems we will have business lounge access and an additional carry-on bag, but our checked baggage allowance carries over from our original economy fare.
Thank you.
