Locking the sleep wake lock screen background? Not login background

[chrisan]

The default behavior of Yosemite is to take your current desktop background, blur it, and set it to the background when you wake your laptop from sleep/screensaver

In this thread https://forums.macrumors.com/threads/1767137/ they found how to keep your LOGIN screen from changing by setting /Library/Caches/com.apple.desktop.admin.png to your choice and then locking it via sudo chflags uchg /Library/Caches/com.apple.desktop.admin.png

Has anyone discovered where the "wake screen background" is stored so I could lock that from changing as well?

Same question man. No one on this planet seems to know.

My wake screen is the same as the desktop background.
