In Appium, is it possible to check that an app's dark mode feature is enabled?

Question

In the app, I am able to go to Settings and turn on the Dark Mode feature.
I want to check that this feature is working and write a test validating that the app went into Dark Mode successfully.

If you know the particular attribute (text or background color, etc) of an element that changes, you can use the Get Element Attribute command

MobileElement element = (MobileElement) driver.findElementByAccessibilityId("SomeAccessibilityID");
String tagName = element.getAttribute("content-desc");
