PS4 Pro support is already a thing in The Surge. You can play in dynamic 4k at 30 fps or get that smooth 60fps at 1080p. Deck 13 just released a patch adding HDR support for PS4 Pro and PS4. The option is available if you have it enabled in your console settings. What are you waiting for (except a new TV)?
There are also heaps of tweaks and bug-fixes in the patch, which you can read all about here.
