generally yes, if the logo is loaded from an internal resource, you 
should be able to override it in this way.

On Windows the msi installer has no images that come from jpackage 
resources, so will use macOS for an example.

I run:

> jpackage --name mjar-test --module me.mymodule/me.mymodule.Main 
> --module-path mjars/mjar.jar --verbose

then as part of the verbose output I see:

so I create a dir "resources" and I put my image file in it as 
mjar-test-background.png then I re-run with command:

> jpackage --name mjar-test --resource-dir resources --module

And now it should create  dmg installer with your customized dmg 
background image.
