We used to be able to get the current profile’s RemoteLoadPath like this, it returns null however since 1.19.4 (can’t be sure about other unreleased versions after 1.18.15).
var addressablesSettings = AddressableAssetSettingsDefaultObject.Settings;
var remoteLoadPath = addressablesSettings.profileSettings.GetValueByName(
addressablesSettings.activeProfileId,
AddressableAssetSettings.kRemoteLoadPath);
