Application.installerName values

https://docs.unity3d.com/ScriptReference/Application-installerName.html lists this simply as a read-only string. What are the possible values for this? For example, can I use it to tell the difference between someone who installed my app from the US iTunes app store vs the Canadian iTunes app store?

 

I think it's not separate in different countries. Think it will always be the same. :-(

 

While not the same, this asset was very helpful: https://assetstore.unity.com/packages/tools/integration/precise-locale-65836
