PS4 had a weird issue with Anisotropic Filtering which resulted in textures being blurred at an oblique viewing angle in the game. This issue mostly affected third party multiplatform releases and it was not until recently that we heard that Sony was looking into fixing it for the developers.
If the recent games and updates are any indication, this issue has finally been resolved as confirmed by updates to games like Devil May Cry and the release of some of the latest games like Mortal Kombat X and Dark Souls 2: Scholar of the First Sin.
First, we have a comparison of Devil May Cry with latest patch, which adds in AF for the PS4 version of the game. Cort Straton, who is ICE Team Programmer at Naughty Dog, tweeted about the DMC AF issue stating that he was glad that this issue is finally resolved.
Well I'm glad that's behind us now. https://t.co/O8Dv4abZ9p

You can check out a comparison between the pre-patch and post-patch version of the game below, courtesy of NeoGAF user RoboPlato.
Left = Pre-Patch, Right = Post-Patch
The difference is pretty clear from these screenshots. The pre-patch version with no AF results in extremely blurry textures at a distance compared to the post-patch version. If you still can’t see it, perhaps you need to take a closer look at the ground as seen in the comparison below.
The other two recent examples are Dark Souls 2: Scholar of the First Sin and Mortal Kombat X. Both of these run with some degree of AF enabled on the PS4, especially Mortal Kombat X is a good case here as it is another Unreal Engine 3 release. This issue usually plagued games that ran on Unreal Engine 3, so seeing that Mortal Kombat X runs with 8x AF on PS4 is a nice sign.
If we talk about exclusive games for the PlayStation 4, most of them managed to avoid having issues with AF and the same holds true for Bloodborne, which has AF enabled in the game.
Lastly, Project CARS developer Slightly Mad Studios confirmed that they have increased the AF on the PS4 and Xbox One version of the game from 4x to 8x, which should result in a better image quality for the game.
