Native 4K or Checkerboard "uprendered" 4k

The jaggies on the shoulder show some limit in the resolution, or in the type of antialiasing used.

Many of the other details, look like better textures as opposed to display resolution issues.  I wonder if they increased the texture resolution or not?  If not I wonder why not.  It may be a technical reason like insufficient RAM, but PS4 has quite a lot of RAM, so I would suspect they just haven't uprezzed the textures as that would mean a rebuild of all the assets and a large download.

The PS4 has a lot of RAM? For ultra textures?

Games can only use 5 GB of the 8 GB. These 5 GB unified RAM aren't reserved for the game's graphics alone, the whole rest of the game uses a part of this RAM, too.

Of course they have to make compromises in texture quality on consoles compared to high end PCs with 8 - 32 GB RAM plus 4 - 12 GB GPU-RAM.

Yeah, makes sense.  It think from these screenshots that's the biggest differential adding blurryness, rather than the lack of native 4k resolution.  It's not going to compete with 6GB+ PC GPUs on texture details.

The geometry edge detail acutally looks really sharp, so if this is the result with checkerboarding it's very very good.
