Where is this 5e Theme located?

[legitomega]

I have seen several streamers and screen shots of groups playing 5e, and they all have this theme. I have looked everywhere i know to look, but can not find it.
Is it a base extension within the game, or an external file i need to download. It looks like a wood theme, with cartoonish icons and pop up windows.

There's a couple of alternative themes here (https://www.fantasygrounds.com/forums/showthread.php?20355-Alternative-Wood-and-Dungeon-Themes)

The theme was a little too close to that of another game (video game) and was removed based on that.
