This mayhem is running on 4.5 GB, ostensibly the maximum possible on the PS4.  Meanwhile, the Xbox will sport an additional half gig of RAM above that.

Instead, developers have a guaranteed 4.5 GB to play with on the PS4, and 5 GB on the One.  Advantage: Xbox.

To be precise one of the killzone slides shows  4736MB or 4.625GB  of total ram usage. So we must think it's at least minimum 5GB usable for PS4 games.

1536MB + 128MB + 3072MB = 4736MB or (more than) 4.6GB ram used in the killzone demo. This 4.5GB used by killzone SF is a myth, it has never been the case, people just never properly added the numbers, they just rounded it down to 4.5GB for their own purposes. You should modify your post accordingly.
