Nah the website references "Victoria Frankenstein" so it might not be using the exact plan for the cinematic universe but it's not based on the boris Karloff era

It's using them as a base, I think, even if it's not 1:1. Like all the concept art it's clearly Karloff -esque, in both his design and set pieces they're showing (big burning windmill). They just decided that women can be obsessive amoral mad scientists too, causa WOKE.
