Of course, the DPR studio scene shows the differences in resolution under idea conditions. In peoples' everyday shooting, one might expect to see much smaller differences.

I'd say in real world environment, the difference is bigger than DPR well-lit lab environment especially in low light between FF and crop cameras. In true low light, FF shows more advantages than DPR simulated low light.

...we have to weight the considerations of DOF and noise for low light photography for any given shutter speed.  If noise matters more than DOF, then, for sure, larger formats will hold the advantage.  However, at the same DOF and shutter speed, the noise will be the same for equally efficient sensors.

In my opinion, when it comes to noise and DOF, most opt for less noise over greater DOF, even given that greater DOF is more desirable than less DOF, which, of course, is why many prefer larger formats for lower light photography.
