Man, in real-time most next gen games look pretty ass IMO.
Most of the screenshots released for a long while were bullshots (Oversampled promo shots=our version of downsampling. Render super high resolution,downsample it)
Killzone Shadow Fall when first shown had really mediocre textures and poor IQ and AA (Only FXAA. DoF is only like Half resolution or even quarter IIRC from the presentation made on it. You can see this on some of the shots i post below)
But the first screenshots released were 4k screenshots and 4k downsampled to 1080p.
Promotional shots- 4k downsampled to 1080p

Most next gen games have crap AA too. Dead Rising 3 doesn't have any AA at all as far as i've seen. Ryse Son of Rome is probably using SMAA T1X because there is still some super obvious aliasing and specular aliasing.
InFamous Second Son has some pretty awful specular aliasing (But doesn't look too bad in motion)

Not even Square Enix's Angi's Philosophy demo had great IQ. In the screenshots they released it's clear their 8xMSAA+FXAA solution just wasn't great. It was really the one area(Besides some shadow map flickering and some low res textures and lighting components) that kept it from looking pure CG.
Some next gen games have some decent new lighting (That's already been possible on PC for a while) and effects and increased Poly count and LOD Systems(That again has already been possible on PC).
Next gen games IQ is not as good as what we can do with current games on PC.
Actually the closest i've seen something get to what we can get on PC is Knack. Almost 0 temporal aliasing from what i've seen and pretty sharp.
But I guess i'm alone in this view. I wish consoles were powerful enough for good IQ and not just fake IQ with shitty ass sharpening like with The Witcher 3
