That would all depend what you're watching it on....... If it's not a HDR premium TV (I. E. Samsung ks series or LG OLED) then you won't see much of a difference. Currently, there are few TVs that give the full benefit.I wouldn't get too excited about HDR. I've played Forza Horizons 3, and also a few 4K UHD blurays on the XBone S. While there's definitely some more colour fidelity over non HDR media, the difference to my eyes is minimal.
