Is the wifi spec or perhaps chip required for it subject to export control?
Well, I have Sony and Samsung (both middle east regions) but they dont have any restrictions in these areas. I only see these kinda quirks with LG all the times.
It's more likely an out-of-date regulatory database that predates 5GHz being allowed in those regions.
Linux's wireless-regdb has proper 5G regulatory information for at least SA, CY, EG, QA, at least since 2017, just checked. The TV in the repo is 2025 year model.
