EV sales, while still increasing have definitely softened. 1-2 years ago there was a big surge as more and more manufacturers entered the market and prices came down.
Sales have softened since. Hybrids appear to be having a surge but too early to say if it will continue longer term. While a lot is simply Toyota sales, it's not all of it.
Having said that PHEV aren't really showing a big change so perhaps it is largely the Toyota effect.
