You're getting into the weeds.
Imagine all the iPhones that aren't on Wi-Fi when they get such an emergency update request: they'll melt the mobile networks trying to download 2 GB each.
The idea doesn't work.
This is why Apple devices check for updates once a week, staggered. The load is therefore mostly constant, other than the hardcore ones who manually check for an update once they hear one is available.

If you look at the network usage graphs from ISPs and such you can see that downloads drop to about 5% of the network capacity at the 00:00 - 06:00 times. There is a lot of spare capacity to push out updates at night which uses a tiny amount of data compared to the video calls and streaming that go on during waking hours. As a side note, upload rates seem to be somewhat constant at all hours. I assume it must all be IoT security cameras.
