I know, I know, this is all very unscientific but remember: you didn't see anything even close to what a 4K HDR output looked like on last night's PS4 Pro reveal.
Each of these GIFs are from a 1080p gameplay trailer for each game: one from new Pro footage, one from previous PS4 video. Even without a 4K monitor/TV there's clearly some improvement, with crisper colours and details.
There are other noticeable differences like Aloy's hair and the textures in Tomb Raider, not to mention more detailed geometry on Elder Scrolls Online. It does look a lot like the difference between the game running on lower and higher PC settings.
Take a look and see what you think.
