Can You Tell The Difference Between 720p and 1080p?

Yes, non native display res always stands out.
1080p vs 720p makes a big difference for racing games where you focus on a small part of the screen looking at the road in the distance. For open world games it adds extra immersion being able to see further. For platformers, no advantage, but looks nicer when it's not upscaled.
