Moreover, FullScreen and Maximize are differentiated by checking if window decoration exists - maximized Stage will have its decoration taking space on top of the screen, whereas FullScreen one will not.

Unfortunately I couldn't figure out why it returned (0, 0, 0, 255) or (255, 255, 255, 255). To mitigate that I moved color checks into separate `runAndWait()`-s with a small sleep between them, which seemed to help `getColor()` return proper values.
