DPI awareness does not seem to be working

[David-Hari]

I recently got a 4K monitor and set the scaling to 150% (actually, Windows automatically decided that was the best scale).
Now when I open System Informer it looks like this:

It's really small and everything is squished up. It should be much larger than that (1.5 times to be exact).
When I log in via remote desktop, from a computer with 100% scale, then it appears regular size.

I can see in the application manifest that dpiAware is set to "true/pm" (i.e. per monitor). I also see in the settings.xml that all size related settings have "@96" at the start, which suggests that it is recording the sizes at the given DPI. I would then expect it to see that the DPI is now actually 144 and adjust all sizes accordingly when it displays the windows.

Am I missing something here, or has DPI awareness not yet been implemented? #1386 is still open but it looks like most of the work has already been done.
I am on version 3.2.25011.
