It will depend on which GPS implementation DJI picks. The normal GPS Systems that consumer products use has a base accuracy of +- 16 ft, 95% of the time. No matter what DJI does, it can never be more accurate. More accurate systems are available of course, but require different hardware and different software to work. Some of theses implementations require a number of readings and averaging to get higher accuracy. This takes time, and cannot produce results quickly enough to integrate into the existing DJI Position integrating system.
