I pulled my personal list of new releases I saw in theaters starting in the fall and marked the ones that had visible diffusion filtration for the bulk of the movie:
Guardians of the Galaxy
The Trip to Italy
The Judge (diffusion)
The Theory of Everything (diffusion)
The Hunger Games: Mockingjay Pt.1
The Imitation Game
Exodus: Gods and Kings (3D)
The Hobbit: The Battle of the Five Armies (IMAX 3D HFR) (digital diffusion)
Big Eyes (digital diffusion)
Into The Woods (?)
Now the ones that I didn't notice camera filtration or post diffusion had various degrees of sharpness and may have occasionally slipped something subtle on the lens for a particular close-up, but I think the differences in sharpness are more to do with lens choice, shooting stop, use of smoke, etc. "Big Eyes" may have also done some optical diffusion now and then, though the DP is well-known for shooting clean and diffusing in post. And I can't recall whether I saw diffusion effects on "Into the Woods", post or in-camera. So much of the movie was shot in smoked stages that it is hard to tell.
"The Judge" and "The Theory of Everything" were the two where I clearly saw the artifacts of lens diffusion, though in "The Theory of Everything" it varied quite a bit, I suspect the use of diffusion was mainly for the earlier scenes.
