Actually, it's worse than not detecting changes, it's simply not getting
the right values at all. If I run the program when the system appearance
is already in Dark mode, it doesn't get the correct values at start up.

I can reproduce this on macOS 13.x using JDK 21.0.2 and the latest
JavaFX. If I run the PlatformPreferencesChangedTest program in
tests/manual/events we correctly detect the appearance changes. If I
first initialize the AWT toollkit as follows, then it doesn't detect
the changes:
public static void main(String[] args) {
java.awt.Toolkit.getDefaultToolkit();
PlatformPreferencesChangedTest.main(args);
}
I'll file a bug...not sure yet whether it is AWT or JavaFX.

Just tested with JDK 21.0.2 and the behavior is unchanged. I don't
have an older macOS version <14 to test whether this issue is
actually specific to 14 or not.

There were changes to AWT in JDK 22 for macOS 14, so it might be
worth trying JDK 21.0.2. In the mean time, I'll do some testing of
this as well now that I know it is related to initializing the AWT
toolkit.

I am using JDK 21+35 and JavaFX 22-ea+28 to run the project on

assume that there haven't been many changes to awt in that time.
Interestingly, I found another issue that occurs when that call to
|GraphicsEnvironment| is made/not made where it is not possible to
quit a JavaFX application via the dock quit operation when it is
minimized to an AWT tray icon. I can file a separate issue for that.

That likely means that initializing the AWT toolkit is interfering

I presume you are using a very recent ea build of JavaFX 22. What
version of JDK are you using?

Well, that is going to be a fun one to debug ... In my
application I check for a headless environment with
GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices().
If you call that one before you initialize your application, the
preferences detection does no longer update. So if you augment
your PlatformPreferencesChangedTest application with this main
method, it no longer works. Also, it throws another exception
when clicking on the fail button.

Since I can't reproduce the error on macOS, it's hard to say what
could be causing it.
If you have the chance, maybe you could run the
PlatformPreferencesChangedTest application:
https://github.com/openjdk/jfx/blob/master/tests/manual/events/PlatformPreferencesChangedTest.java
That might rule out that the differences we're seeing have anything to
do with the way we're using the API.

I checked again, restarted everything, but still the same problem:
Furthermore, I also tested it on my Asahi Fedora Linux with the latest KDE
Plasma. The preferences values there are all detected correctly, but are never
updated at runtime when changed in the settings menu.
