That may be true for other eink readers, but on the 7" Oasis the inverted mode is done in hardware. Black and white are simply switched. A black flash full refresh in normal mode becomes a white flash in inverted.
Even if refresh is turned off in settings, leaving the menu will always do a full refresh. So if there is ghosting leftover from the menu, then the screen is defective and should get replaced.
