I think the differences from 900p upscaled to 1080p and 1080p is not important at all.
The only reason some people are counting pixels is that you CAN count them.
"better graphics" was and is always a matter of taste. There are things like lighting effects, artstyle, animations, facial expressions etc etc and IMO all of these things are way more important than resolution. But all of these things are based on personal preferences. Resolution is not. That is why people use it today.
Resolution meant shit last gen. If you asked for the best looking game last gen, very few would mention Wipeout, because it runs at 1080p.
I am not getting tired to mention that MY personal best looking game of last gen is Fable II, because the artstyle and the atmosphere just felt special and really was a beauty.
Maybe I am crazy, but I still think that The Last of Us, Halo 4, Gears of War 3 or Uncharted are great looking games and not one of those games was able to get past 720p at all. I still think X for Wii U looks really really good, but I am not into JRPGs.
Gameplay > visuals and for the visuals the resolution is the least important aspect.
Imagine not having GamePass on your console...
