AU - odd discrepancy on lock screen

I've updated two of my computers to UA now, with good success (so far, at least).

One is a laptop running 10 Home, the other, a desktop/all-in-one running 10 Pro.

On the laptop, when I click or slide the lock screen up to log in now, the background picture stays and the login screen (PIN/Password) is transparent over the picture.

On the desktop, it still goes to the solid theme color I've set to enter my credentials.

I don't think I changed a setting on the laptop, but if I did, I don't know what it is! I like the transparent login and would like to put it on the desktop. Anyone know what setting that might be?

Thanks!

Settings -> Personalization -> Lock Screen
In there: Show lock screen background picture on the sign-in screen

Not there on the desktop (Win10 Pro). Any idea where to look for it?

Yep, that's where it is on my laptop. But it's not there on the desktop (Win10 Pro) version.

So, the question is, is there a group policy setting or registry setting I can change to enable it in Pro?

It is there on all of my desktop Win10 Pro.

OK, I get that it's there for others on Pro, but the question is, how do I get it to show up on my version??

This is really strange. I have exactly the same problem on my Windows 10 Pro laptop but everything works fine on my Windows 10 Pro desktop.

Have you found a solution yet?

No, no solution yet.
