Not really. It no sold multiple Abstracts including ones with Multiversal feats, sent out a blast to the beyonders realm which wrecked it, and when Adam Warlock and LT confronted eachother, LT said a battle would lay waste to all realities, which indicates the IG being Multiversal.
This is of course if were talking about the Classic IG. The current IG got broke by Captain America :P
IMO we can call it a retcon. ;-)
