"The field of view (FoV) is the extent of the observable world that is seen at any given moment."
FOV is better characterized by a 2-dimensional measurement, like square degrees, or steradians, than a single 1-dimensional measurement, like diagonal angle. "2x improvement" sounds like a perfectly valid way to describe a 2.4x increase in FOV area to me.
