Is the Dawn Wall both 9a and 9a+?

Fanatic Climbing presents an interview with Tommy Caldwell and Kevin Jorgeson in regards their Dawn Wall ascent which has become a movie. Interesting is that Tommy had to do a variation pitch, including down climbing, as he could not do the dyno going more straight up. In fact, they say that either Chris Sharma and Jonathan Siegrist could not manage the dyno and even Adam Ondra did choose the loop pitch. In the topo, both the loop as well as the dyno pitch are graded 9a but in practice, Jorgeson's straight up pitch is probably more like 9a+?
