Free version of MaxMind's GeoIP - a lot of services use them but the free version is the most inaccurate. That being said, not sure it's a mistake on the EU thing?
Presuming that the "in-EU" is actually meant to refer to "subject to most EU legislation, and in particular the GDPR", then it's incorrect in the opposite way for Norway: it shows false.
Perhaps you ought to open one for Norway? (I don't think it would be appropriate for me to do it because I am not seeing the issue, not being in Norway.)
> Country United Kingdom
> Country (ISO code) GB
> In EU? true
Well, that's inaccurate for a start.
