There is no downgrade it''s the same build with different video quality:

Now notice the interface for E3 2016, TGS 2016 and EGX 2016 is the same right? Now look at the game informer footage, the UI was slightly updated. What I'm saying is that the E3 2016, TGS, EGX and Tapei are the exact same BUILD. So how could it be a downgrade if it's the same thing?!
Also, compression doesn't remove detail at all... right?! What a joke, just compare the E3 2016 pic and the EGX one, it's night and day even though they're showing of different things.
