Using installerName to detect apk downloaded and installed from 3rd party websites

I've been saving installerName(https://docs.unity3d.com/ScriptReference/Application-installerName.html) for the past some time.

Here's some values from it for a few days: https://i.imgur.com/GLUMeBP.png

If value is empty, does it 100% mean user installed it directly from downloaded apk file?

Could it be that on some android devices this value is always empty, even if it's installed from play store? Or it changes to empty after user updated the app?
