BA WTP seats are only a very slight improvement over economy. In fact, on a night flight, if you hit lucky in WT and have an empty seat next to you then you can at least lift up the armrest and stretch out a bit. No such luck in WTP since the armrests are fixed.
Food in WTP is, as correctly stated above, exactly the same as WT. Very galling when you can smell the hot bacon rolls being dished out in the Club World cabin just in front. For the extra five or six hundred quid a WTP seat costs, a bacon roll (and a smile from the cabin crew) would be nice!
