How to find what texture compression was forced for build?

How to find what option was set to compress the texture in Build Settings, when the application is already running on Android?
Something like EditorUserBuildSettings.androidBuildSubtarget, but from a device NOT in the editor. I can save that data at build time and read it afterwords, but I wondered maybe it is marked somewhere already (AndroidManifest ?) so I can read it at run-time.

You can find it in element of Android manifest: <supports-gl-texture>  |  Android Developers
