I use the Aeriel screensaver that uses the same high resolution animated images Apple uses in the Apple TV screensaver. Some of those are stunningly 3D on a 4K monitor and I wish I could capture some of those of a desktop.
command-shift-3 captures my screensaver as a .png which can be used as a desktop. Is that what you mean?
