Unity not showing 9 Patch .png as Android Splash image

Greetings.

I’m working in an Android develop, and I needed to guarantee that splash image won’t be deformed by scaling, and I’ve found about draw9patch. But, after making my .9.png splash image, I load it at the Player Settings, but the image won’t show. Guess the extension is the problem, since any other regular .png image will show, but, since Android build does not have an option to specify different splash screens, as iOS build does, I had to resort to 9 Patch.

Any pointers?

Thanks in advance.

Currently I am looking into using the following solution:

Using that solution for the background color and making a transparent png with my logo appropriate space on either side I am hoping will do the trick.
