Not sure how the question relates at all to what I said

You said that DR depends on sensor size and efficiency. The two sensors are roughly the same size (LX3 sensor is technically a tiny bit bigger, but is never entirely used) and the very close SNR would implicate similar efficiency. Yet the DR is very different...one stop is quite a bit. From your point of view the DR should be the same.

That's how it relates to what you said.
