From (very) brief searching, Adobe Camera Raw produces a depth map (and lets you edit it), and gets situations wheee the same pixel contains hair and background wrong, exactly the way one would expect if one trying to use a depth map-aware blue. I would expect an ML algorithm actually trained to blur the background behind hair to be able to do better (where the resulting image is the output), and maybe a radiance field or splatting algorithm could also do better. In the latter cases, the hair would be separately represented as a foreground object/source. I could easily be missing something, though. And I did not find any good full-resolution examples.
