Configuration override not work from settings.php I add the following to the end of my settings.php

$config['system.site']['name'] = 'Drupal 8 DEVELOPMENT';


When I run drush cget system.site name it still displays the old site name.  

Any idea why it wouldn't be overriding?
You can use the --include-overridden option to show overridden config, for example:

drush cget --include-overridden system.site name
