Android - Google Maps Api can't change default background color

My whole app design is based on dark colors, so I also customized Google Maps using mapstyle.withgoogle.com but when I start the MapsActivity the default Map Background color is still bright until it fully loads as you can see in this EXAMPLE GIF

**This bright background also appears when I zoom out the first time after the Map is loaded!

Is there a way to change the color of that splash screen, background or Map placeholder(how can we call it)?

Here's my custom MapStyle that I created using mapstyle.withgoogle.com
