It doesn't decrease the DOF at all since that's a physical distance independent of viewing size.

Sorry, wrong answer.

Magnifying magnifies the blur circles too, which makes circles visible that aren't visible without the magnification. In other words, it changes the CoC, which changes the DOF. At high magnification, the blur circles are bigger and easier to see, thus you have less DOF.

See? These are just differently magnified views of the same image.

Those examples represent different output sizes, which this isn't about.

Magnifying an image in the viewfinder is the exact same thing as magnifying them on your computer screen.

This was about seeing the DOF that the sensor sees.

There's no such thing.

What you can see when magnifying, you can see in the final image if printed at a large enough size with a close enough viewing distance to see all the detail captured.

And can't see if you print smaller.

If the size is smaller than that and/or viewing distance larger, the whole discussion becomes moot anyway, since these minute differences become irrelevant to begin with.

No, the DOF just gets larger.

But you're free to throw in more theoretical differences.

It's not theoretical - it's absolutely real. A 5x EVF magnification is the same as a 5x larger print size or a 5x smaller CoC.
