IMHO - LH is not replicating BA's effort because of an innate "arrogance" in thinking that they are the best and they will lead the market, not follow it. Therefore LH clients are willing and eager to pay a premium for a non competitive product, including from/to ME3.
This reminds me how LH, in the far past ( early 90's) were having the same attitude in not wanting to discount the product - in any case. And here we are with the 99 euro nonstop you crowd. ( and the 123 euro "taxes" on awards!)
