That is the impression that I get, the country code info is part of the management frames transmitted by the AP, could be unsupported, not configured, or mis-configured.

Should be part of the 'beacon' info. https://howiwifi.com/2020/07/13/802-11-frame-types-and-formats/ has a good overview. I discovered this exchange while observing 'on the wire' with wireshark.

> Am I looking in the wrong place for REGDOM events? Is there another wpa_supplicant instance that's setting things correctly?

It's the right place but wpa_supplicant has to interact with a variety wifi chipsets with varying firmware/drivers in play, would not surprise me if things are not consistent across the board. There also the difference between NetworkManger 'user connections'/'system connections' but that should not matter as NM passes the wifi info to wpa_supplicant directly.
