And for me the image is shown at 120dpi, because that is my display setting. If
I change my Windows 10 to use 96dpi, then the image is shown at 96dpi.

LibreOffice uses what ever dpi is set in the OS, in case the image has no dpi
info. But the user cannot see, that the image has no own dpi information. So it
might be useful to change the text in the crop tab of the Image properties
dialog. For example instead of (120dpi) write (unknown dpi, using 120dpi OS
default).

In file format only the current size and the crop-values are stored.

LibreOffice does not change or set a dpi-value at the image.
