Actually Arrowverse is defined as a Multiverse. Flash as series firmly exploring that and confirmed within the settings. Just being another dimension isn't an issue proven by the fact Flash and DC's Legends of Tomorrow dealing with characters from other dimensions on more than one occasion it'd merely make them Alternate Reality when other villains did a Dimensional travel.
