And yet you said:

So the Rohloff is that much more efficient than a BWR? I have a little trouble believing it's
that much better.

I don't see a derailleur system that can handle a mondo cassette like those playing well with 16" wheels. 20" yes,but not 16".

I'm calling balderdash. We have a BWR here,and my Park Tool scale says it's .95kg.
Rohloff's site says their hubs are between 1.7 and 1.825kg. That's a pretty big difference,over a pound and a half,pushing two pounds between the two hubs. Even with the 11spd parts,I can't see how you only saw a 150g difference.
