Mode detected is always light even if the background is black

Issue

I did a test on my MacOS Sequoia 15.7.3` using the simple code example

///usr/bin/env jbang “$0” “$@” ; exit $?
//DEPS com.github.Dansoftowner:jSystemThemeDetector:3.6
//REPOS https://jitpack.io

package dev.snowdrop;

import com.jthemedetecor.OsThemeDetector;

public class ThemeDetector {
    public static void main(String[] args) {
        final OsThemeDetector detector = OsThemeDetector.getDetector();
        final boolean isDarkThemeUsed = detector.isDark();
        if (isDarkThemeUsed) {
            System.out.println("The OS uses a DARK theme");
        } else {
            System.out.println("The OS uses a LIGHT theme");
        }
    }
}

and I always got as response: LIGHT
