That seems to be a minor matter. Of course at best some measurements

This claim would apply to all ranges. There seems to be evidence it is
unfounded.
The main argument for using the range interface for RNGs is reuse of
abstraction. Minute implementation matters are much less important. The
main counter-argument is that the abstraction is not fitting well and
another abstraction (such as opCall) is more advantageous.
