Get Property Privacy UserProfileService.asmx Sharepoint 2013 Office 365

I'm trying to get properties privacy from UserProfileService.asmx.

Infos:

Sharepoint 2013 Office 365, Provider-Hosted App using c# 

I'm global administrator

Sample code:

PropertyData[] userProperties = _userProfileService.GetUserProfileByName(loginName);

var firstNamePrivacy = userProperties[2].Privacy;

But i'm always getting privacy as "NotSet", even if it is Public or Private on my Sharepoint profile.

Anyone knows how to solve this problem?
