Certainly, there are lots of apps leveraging the TrueDepth sensor on iPhones that reach an even higher level of fidelity as far is pose estimation is concerned.
The limiting factor for accuracy in a lot of these technologies is the actual rigging process of the characters, probably because that is very difficult to standardize or generalize across different geometries, art styles, animation drivers, 2D vs 3D, etc.
