You can't possibly tell from that angle view with respect to the normal of the water surface if it's ray-traced or SSR. That angle could show SSR being identical to RT. The only way to know for sure is if the camera was lowered to nearly perpendicular to the normal on that water and see if the reflections start to gradually fade out. If it was ray-traced, they certainly rendered that scene at one of the smallest resolutions I've ever seen in a game with RT reflections in order to take advantage of not being able to fire multiple rays (which would induce noise) to create a real blurred reflection.
Again someone from Insomniac confirm they use raytraced water.
