Yah, it certainly seems like maybe that was peak pricing. This write up has some more data on historical pricing https://www.ipxo.com/blog/ipv4-price-history/ I've also heard folks pay quite a bit over the average price for novelty IP addresses, so perhaps that skewed the data? I'd love to be able to buy 2.2.2.0/23 or my favorite 42.42.42.0/24

Yeah, one example is Cloudflare and 1.1.1.1; though the story behind that is less about money and far more interesting. Apparently, APNIC had owned 1.1.1.1 for, basically, forever, but were never able to actually use it for anything because it caught so much garbage traffic. Cloudflare is one of only a handful of service providers that could announce the IP and handle the traffic; so in exchange for helping APNIC's research group sort through the trash traffic, Cloudflare hosts their DNS resolver there.

I would really like to see the results of this research to understand what is going on there.

So, what happened to everything that expected 1.1.1.1 to error out and now is getting something?

(not worried about them, just curious)
