Only on a binary scale. There's even among actually funded companies better or worse pitch decks.
You can often just get funding by having a good team matched to a VC that knows your industry. Pitch deck can be crap and other VCs might hard reject.
Another potential methodology flaw is that they don't seem to group decks by VC industry. I definitely altered my deck for different VCs, in ways which could make it a worse deck for the "average VC". GPT-4 might be better at setting context that industry expert VCs don't need - meaning this isn't even comparing like and like.
