Just to be clear: this Bishops vs Knights was for the version of the Knight that was enhanced by 4 extra non-captures (Betza NmH), and not the Omega-like NmZ? I guess you are seeing the effect of the Bishop pair here; for a plain Knight in Capablanca Chess I found N = 3, B = 3.5 for alone Bishop, but a bonus of 0.5 for having a Bishop pair. (Interestingly enough that bonus disappeared almost exactly when the Bishops were started on the same shade.) So the BB-NN difference there would have been 1.5 Pawn. I am surprised that is stillseems larger than a Pawn here; I would have expected the Knight enhancement to have more effect. But perhaps the Knight suffers from the deeper board after all. (Although this is exactly what I would have thought the enhancement would be able to prevent.)
