Tried to mimic your pictures on the PC version. Used Garden Ops to take mine and for whatever reason custom FOV doesn't work on that mode so it's on the default 70.
Fog might look slightly better on the PC shots, also a noticeable difference in foliage. Course your shots are compressed so it's not a perfect comparison.
Actually I'd say the fog looks better and more plentiful on the PS4 version. Definitely a difference in grass quantity in favor of PC, though.
