I agree with you, I think it should have "EMC certification pending" sticker. But non-official QS, that is to say, QS from AIB normally has no such sticker.Are you sure? ES/QS usually has "Not for EMC testing" sticker on them, but those Titans X had no such sticker. Also from the left they have a big retail sticker with model name and S/N, PCB made in China, ES/QS often are made in Hong Kong or USA (but not always). I think it's a special OEM card.
