Usually when people start posting images with no context and asking, "Guess me", it's because they personally don't accept or understand the the math, or have never recognized it's practical application in their own shooting. Do you not accept the math, Aristophanes?
I accept the math. In fact, I started this with saying it's math. My contention is that the math is not so obvious as to make much of an aesthetic difference.
It's like trying to tell if a golf shot from the tee is 120 yards or 110 just by eyeball.
There's little empirical evidence that the math makes a huge difference in people's perceptions of a photograph. Those that claim to see FF differences usually have internalized the metrics with their own work. We cannot measure DOF with our eyes. And when we try, we usually get into discussions about lens and softness/sharpness etc. long, long, long before we get into sensor size. Or film size. The bokeh on my film shot is remarkably closer to that from an APS-C sensor. It could easily have been from a DA 70/2.4.
There are too many variables at work to conclude that aesthetically one needs to have FF DOF. Frankly, APS-C lenses often have better bokeh IMO, in the same way that 135 lenses have better bokeh compared to a lot of MF glass. But that's just my generalization which varies from shot to shot and photo by photo with huge variance.
And because people cannot tell readily or without argument and guessing games, it acts a a brake on FF sensor development. The argument for FF DOF is not convincing because it is inconclusive. It's another reason why there's no race to make everything FF. Added DOF is probably down on the list of reasons from a market perspective.
