It is currently impossible for display extenders to be set on the Default view, and reused on other unoverridden aliases.
Contrary to what the UI would have you believe when you are editing "All displays" display extenders, it only affects the single display.
The display extender won't apply on other variants of the view.

I just ran into this. It's certainly confusing in the UI, because I change an extended setting on Default, and when I go to any other display, it is italicized as if overridden, whether it has the same value or not. Then, if I try to "revert to default", it does nothing.
