Dynamic formatting of measures that return a date is not possible. When creating a measure that returns a date, it is not possible to enable the dynamic format, while there are several use-cases where this would be relevant. Then, I tricked PowerBi into enabling dynamic formatting by first creating a numerical measure then setting formatting to dynamic and setting the format string, and then changing the measure to the actual measure, it results in weird behaviour: Format string: Result, showing "Oc" instead of "Oct": However, if I keep the date to a numeric value (so measure: "TEST = 1* MIN(SalesOrders[ShipmentDate])", the behaviour is even more unexpected, the same dates as above then result in this: So clearly, dynamic formatting in such cases does not work as expected while it would solve several issues. (Note: I'm aware that this example could be achieved in much easier ways, but the actual use-case is more complex, but not so relevant for this idea)
