There is a video by ghostrob in 4k. But I can tell you first hand after playing it on the PS4 pro and on a 4 k monitor that no video does it justice to how real the lighting makes this game look in 4k. During the EA access version, I was playing on an Xbox one. Some teams did not look that great in certain lighting. On the PS4 pro those teams looked amazing and the colors really pop.
Some people say they haven't noticed a difference on the PS4 pro, but you need to be playing on a 4k TV or monitor.
