OP specified "Campaign"... Is there a MP campaign in COD?
That would be a first and a welcome addition if it is the case.

OP: Even if the PS4 version should not be slower in any case (with the same graphic settings). Maybe Microsoft worked very closely with them to achieve this at least. All in one, the experience seems to be awesome on both console so no big deal, just surprising.

It's almost impossible to tell the difference in res comparing both, so serious question why didn't they make the PS4 dynamic also to match the frame rate?

Framerate > resolution.

If they couldn't maintain 60fps on PS4 they should have implemented dynamic resolution there too.

this is far from the truth.

but whatever

WOW This is solid data you are posting here to backpu your claim :)

Nah. Maybe for you. Anyway a few occasional drops in framerate (in a singleplayer) isn't going to be much noticable to much people; unless it spikes a lot - which it doesn't. Its fine.

60-40fps is not minimal for me... even if it happens only one time I will notice.

In SP could be a minor but  in MP can cost your life (or kill).

doesnt worth discussing with. watch the video.

The framerate issue on PS4 and/or tearing issue on Xbone in CoD is definitely nowhere close to Titanfall levels.
