In Overwatch it was when I tried that a few years ago. While Atmos gave you some sense of vertical positioning generally it wasn't correct and I struggled with positioning. Theoretically Atmos ought to be miles better, its object based like the sound cards of the early 2000s but in practice they have got something wrong in the headphones implementation and positioning is hard to pick out. Its better than just stereo but the positioning is a lot better on the Sennheiser device.

Whether Dolby Atmos has improved since then or other games have implemented it better I don't know. I feel like we probably need an open source implementation middleware for object sound to headphone/surround speakers to really fix the situation.
