Have you actually played control with RT reflections on to see how and which objects have reflections? Pure concrete that is not wet won't just have a stark reflection on it willy nilly.I am still disagree with you on that. Yes, real world is more shiny than what game tends to represents, but the effect in Control is still too much, especially on matte surface like concrete.
The thing is, there is a big impact between the viewing angle and reflexion. For exemple, in my office, this is a wood flooring. If the viewing angle between me, the floor, and the object is close to 90°, almost no reflexion. But if I do the same thing while crouching, I can see the reflexion becoming more apparent. If I lie down (while managing not to be seen by my coworkers), so the angle is almost 0°, this is a reflexion fest.
But I don't think RT managed that and this is why it is a reflexion fest not matter what is the angle.
Also the game's RT reflections by their very nature include the effect you are talking about. THe Fresnel Effect.
