That is what I also think. Samma Ditthi is complete at the Arahant stage. Before that any person will have some minor wrong views left. This can happen for example when you find yourself in a discussion about some worldly stuff and you realise that it is actually total nonsense to have any view about this stuff. So there is this minor wrong view. It does not change your big picture about this world, but it is hidden and pops up with a trigger. But one should note the wrong view and it gets weaker. Sati must be there. This keeps one on the path.
