I'd love to see a source for that.

This article from 1999 I found suggests that South Korea was worried about North Korea's preparedness for Y2K, https://www.deseret.com/1999/12/17/19480898/s-korea-worried-.... That seems to suggest that South Korea itself would have been making sure its own systems were secure.

Is it simply possible that most of their systems were newer than those in other countries, so updates weren't necessary?
