While Joe Belfiore confirmed sometime ago that both “Translucent Tiles with full background (Windows 10)” and “Transparent Tiles with background on tiles (Windows Phone 8.1)” options will be there in future builds, leaked screenshots reveal that there is one more way in which you can set “Tile Transparency” in Windows 10 for Phones future builds.
As you can see in the above screenshots, while there is option of Windows Phone 8.1 kind of Tiles transparency there are two options to fine tune Tiles transparency in case of full background”. You can make it less or more translucent.
