I still don't understand why they are the same for you .. I added korean-fallback to my local fontconfig and ran in the Korean locale (changed my windows region to Korea and rebooted) and they are different for me.

What I do seem to be seeing is that because we now have UTF-8 as the default encoding and that we have no 
UTF-8.ko that it goes the fallback route .. and so although you get korean by fallback it prefers Chinese and Japanese fonts which isn't right for a Korean locale

I believe we need to add a line like the ja one 
sequence.allfonts.UTF-8.ja=alphabetic,japanese,dingbats,symbol
+sequence.allfonts.UTF-8.ko=alphabetic,korean,dingbats,symbol

[See https://git.openjdk.java.net/jdk/pull/8662 for more info and we likely need to do more of these lines and perhaps you need that PR pushed to include in your testing .. alas I don't even have a single approver yet, so nowhere near the two I need !]

.. even without that I was OK perhaps so long as the fallback seqeuence had "korean" - I'd have to re-test that

So I don't know if that will cure  them all being the same for you but it might.
