Detect if an Android app was downloaded from Google Play vs Amazon vs Other

Question

I know this is probably a longshot, but is there any way to detect programatically whether an app was hosted on the Amazon apps store vs on Google Play? I would like to link to

As of just recently, the Amazon Appstore returns sane values for PackageManager.getInstallerPackageName()

PackageManager pm = context.getPackageManager();
String installerPackageName = pm.getInstallerPackageName(context.getPackageName());

if ("com.android.vending".equals(installerPackageName)) {
    //do google things
} else if ("com.amazon.venezia".equals(installerPackageName)) {
    //do amazon things
}
