No it depends on the respective command. Eg: http://grass.osgeo.org/grass70/manuals/v.distance.html#notes "In lat-long locations v.distance gives distances (dist, from_along, and to_along) not in degrees but in meters calculated as geodesic distances on a sphere. " Regarding r.stream.distance one would need to check the source code (and then document it).
