Yes. But on average the difference in DxO measures is less than two stops since smaller sensors tend to be more efficient than larger. See here:


You've compared DR while I'm comparing low light sensitivity which seems more relevant to total light collection.

The measures I used reflect more or less pure light utilization (the third) as well as a combination of light utilization and read noise (the other two) at low as well as high ISO. As you can see, smaller sensors tend to be more efficient than larger regardless of which of the three méasures you look at.
