Absolutely. So these figures should be regarded as conservative.

The logistic growth model is just the default model choice for 
predicting new-things-replacing-old transitions. Any number of things 
could make the transition go faster, particularly, as you say, pushes by 
major platform vendors like Apple, and the move to mobile first in the 
expansion of the Internet in the developing world. Companies like search 
engine providers and streaming video providers could also exert pressure 
to speed up the IPv6 transition, if they wished. Also, passing 
psychological thresholds like 50% or 90% -- or even just fashion, in the 
sense of decision makers wanting to be associated with success and the 
future, not the rapidly contracting legacy of the past -- might have an 
effect to accelerate the eventual collapse of IPv4 traffic volumes.

I can only imagine the scale of the schadenfreude IPv6 proponents will 
be able to feel once they're able to start talking about IPv4 as a 
legacy protocol.
