Even gaffers can't see the decrease... We literally wait for DF or pixel counters to tell us which games aren't even running at 720p, from which ones were. And spreading the word doesn't really affect people that are already playing the game and enjoying it regardless of what the resolution happens to be. Almost nobody on GAF caught on to the fact that COD4 wasn't 720p until pixel counters told them so. It took pixel counters for people to find out Halo 3 and Reach weren't 720p, and many more examples. Although, to me, it was very obvious that something was up with Halo 3 from the get go, but I didn't know what it was specifically.
And it's going to be even harder to see the decrease this gen, since games will likely be utilizing dynamic resolutions. It's a Directx 11.2 feature and perfect for the display planes on the Xbox One. In fact, I think the Directx 11.2 feature exactly describes the Xbox One's display planes. It'll be so much easier to hide these things this gen. We will have to rely on pixel counters yet again. For example, nobody realized that Killer Instinct wasn't 1080p until a dev apparently said so, although I don't know if it was ever confirmed. I have doubts that Ryse can look as good as it does on the Xbox One while being 1080p, but I guess we'll see.
Also, someone link me to the uncompressed and high quality vid of Infamous. I need to show a relative that's visiting this game, but I don't want him to see some compressed youtube crap. He wants to just watch it on youtube, but I'm not having any of it. Poor fool doesn't know any better.
