You lost me here. At the same ISO and shutter speed, f/2.8 is f/2.8 on any camera, and f/4 is f/4 on any camera. DOF will certainly vary between formats, but unless I misread you, you were referring to exposure. the "exposure triangle" is format independent, which is why it is so useful.
Exactly. Any difference in exposure is probably due to differences in the meter mode and how the individual manufacturers handle metering. It’s not the lens.
