just tried your project with Creators Update ISO from MS MediaCreationTool.
Finally one working with high DPI out of the box! Thanks.
Some usability suggestions.
Ideally one should set the ISO folder and go. Instead there are a number plugins pre-checked with annoying warning, unless you add related software. Also the ISO did not work with my VirtualBox VM. I had to struggle a lot to realise that the ISO is intended for old BIOS firmware. I set first "UEFI" and then "Both" in the ISO output plugin and both options worked with my UEFI VM. I think that "Both" should be the default nowadays.
IMHO small WinPEs should be more widespread among non technicians. In my case, just wanted something to put it in my pocket before travelling (just in case). Most people don't have time to relearn everything because MS has encrypted a couple of files. So kudos to winbuilders... but let's make it just a click away.
Thanks again for your efforts.
