While having no knowledge of internal workings of BA I would say not until a lot more aircraft are fitted out. Reasoning being, look at the direct competition. Although you can get EK and other connecting options which people may rate better than BA, the only "direct routing" competition is QF where they use the A380 which does not have direct aisle access.

You also need to look at fleet utilisation, from memory it takes 3 frames to do the route. BA would get a better rate of return with the limited frames by using the on routes which only require a single frame to operate.
