Bottom line: the 2019-20 season is the highest in terms of the absolute death toll, but not more than by 15% (likely less than that if population adjustment were done).
That being said, "extra death" definitely has a weird, unusual distribution that in all likelihood is related both to COVID and lockdowns.
