The godsphere can't be 1-A for the following reasons
The sphere of gods has shown measurements
Effects of gravity
Apokolips (a realm in the sphere of gods) is said to exist in it's own private dimension
Apokolips can be reached via extra-dimensional portals such as boomtube
Wonder Woman travels to the godsphere and can only interact with the shell of Tezcatlipoca due to his extra-dimensional nature
Darkseid's Omega Beams teleport people through time and space.
With this in mind, Darkseid's omega beams sent Lex to Apokolips
The sphere of gods is a higher vibratory realm. DC follows M-theory in which
vibrations are within dimensionality.
The mobius chair which rides the dimension winds of time and space can travel to Apokolips and new genesis
So they're not above all dimensional extensions which is the requirement to be 1-A.
