Change color initial background

I'm trying to change the background color does not work (Cordova 6.4.0)

<preference name="SplashScreenBackgroundColor" value="#FFFFFF"/>

I pass my configurations in config.xml:

<preference name="SplashScreenBackgroundColor" value="#FFFFFF"/>
<preference name="SplashScreen" value="screen"/>

Always, even if you change the values, it shows the default background color ( # 464646 )

What can happen?
