Is it possible to disable wallpaper cropping on Win10 logon screen?

Question

Windows

Colleagues,
We currently have Windows 7 in our organization. On them, the image on the logon screen is changed by policy. The logo of the office is usually placed on the image and sometimes some information is hung. On Win7, the picture is stretched depending on the resolution of the monitor, so one way or another it is displayed in its entirety.
Now we are moving to Windows 10. On Win10, the logon screen behaves differently. I see that Windows stretches the picture in height and crops it on the left and right. Accordingly, part of the picture disappears on some monitors.
Maybe someone has experienced something similar? Is it possible to somehow solve this or do we need to reconsider the approach to the design of the picture?

In the folder C:\ProgramData\Microsoft\Windows\SystemData\S-1-5-18\ReadOnly\LockScreen_Z and LockScreen_P there are generated pictures for each resolution that was used on the computer. I also encountered a problem that the picture on the lockscreen on Win10 may not be updated. To update, you need to clear the folders with pictures.
I made this script for myself. Group Policy places the image in C:\windows\web\screen\backgrounddefault.jpg, and then it is copied unchanged under different names.
If the picture is smaller in height than the monitor, then it will shrink from the sides and fit entirely. If the picture is larger in height, then compression will not occur and the picture will be cut off at the top and bottom, but will enter the monitor on the sides.
