I wonder if the move to hybrid estates (virtual + on prem + issued laptops etc) is the cause. Having worked in only on prem highly secure businesses no patches would be rolled out intra week without a testing cycle on a variety of hardware.

I consider it genuinely insane to allow direct updated from vendors like this on large estates. If you are behind a corporate firewall there is also a limit to the impact of discovered security flaws and thus reduced urgency in their dissemination anyway.
