Not a single OVF found in a DSLR will represent the DOF accurately at such an aperture. Biggest reason being the ground glass. An EVF will represent the DOF as it will be captured.

No, it won't, for at least two reasons. First, the displays don't have enough resolution to prevent sampling blur from adding to OOF blur.

Yes it will and if the sampling blur would make any visible impact worth noting, the second point that you didn't quote comes in for a rescue.

Second, DOF can't even be defined at capture time, much less displayed, because it's dependent on the final viewing size and distance, neither of which are available at capture time.

In theory, in practise that is only an issue if these were constantly changing to begin with, in which case the whole DOF preview on DSLR's becomes a laughable point anyway.
