Not sure about that, maybe inside the team. When talking to the media and to the outside world, Rogič usually doesn't try to run away from the favorite position or to make excuses. Roglič sometimes does mention he behaves differently, concerning the inner team dynamics, compared to the communication to the outside world. Hence if he is saying he still suffers from the crash i don't have any particular reason not to believe him.
P.S. The good thing is he was in great shape already, before the crash, and the crash could prevent him to peak too early! But likely not, he likely would be much more happy to train at full intensity ATM. That is just how he rolls.
