title: Android TV App Development - Change system settings with Kotlin/Java
body: <p>I am trying to create an Android TV app to change Picture Settings from my App.
  Like adjust brightness, contrast etc.</p>
  <p>I am not able to find any relevant documentation about how to change these settings.</p>
  <p>Please let me know if it's possible.</p>
  <p>I have tried to use the <strong>Settings.System.SCREEN_BRIGHTNESS</strong>.</p>
  <p>It works on mobile but is not working on Android TV.</p>
  <p>OS: Android TV 10</p>
