How do I change the backdrop color in the main Viewport?

CA415

I can't find the backdrop color setting for the main Viewport in DAZ Studio 4.8.

The online reference guide does not apply to version 4.8 - there is no black right-pointing triangle next to the Camera drop-down list.

Go to enviroment. Click Type and choose backdrop. Select a color in background.

On my layout, I go to Window, Panes, and then environment.
