When watching direct comparison videos path tracing was slightly better when someone pointed out more accurate lighting details but not in a way that was noticeable if someone didn't point it out.
What I found works for path tracing is objects that don't have strong textures or bump mapping. I've tried this when writing my own path tracer in a programming project (not cyberpunk) for simple monochrome spheres. Then in that case it makes it look very real, but in something as visually detailed as cyberpunk it's barely noticeable.
I also think the lighting in cyberpunk is too urban and neon. It's not something our eyes evolved to interprete with extreme fidelity so our brains cant really see the difference. I think the effect is much more noticeable in environments with fewer light sources and light sources that aren't neon. For this reason I suspect red dead redemption 2 would benefit much more from path tracing.
That's just my opinion. I have a 3090.
