Probably. But then I would have been upset with the budget for the "fantastic beasts" that's supposed to be the backdrop if not the feature of all these movies. The magical creatures are supposed to front and center in this series. But so far, I feel like they have been somewhat of an afterthought or shoehorned into the movies. However, they have looked fantastical. Don't know if that happens if it's a tv series but you're probably right.
After all, I've been hoping for a HP reboot as a TV series. I think it's time. The movies were great but they left out so much. Each book literally covers 10 months as the kids go from end of summer, school year, then to the beginning of summer. Perfect for a series! 7 years and the source material is complete (looking at you GoT).
