So BA has 2 different club Europe and 2 different euro traveller cabins (with seat type varying by row number) 2 types of longhaul premium economy 2 longhaul economy with 3 (4?) different types of entertainment. 3 types of long haul business with equally diverse entertainment. Two types of F with three types of entertainment. A mid-haul product that is none of the above and a separate airline with three completely different cabins operating from a different company.

It's basically cabin bingo wherever you fly on BA so just go with it!
