Thanks for a great plugin! Running this with Bedrock, I noticed that the following snippet returns WP_ENVIRONMENT_TYPE for both conditions:

	private function get_env() {
		if ( function_exists( 'getenv' ) ) {
			if ( getenv( 'WP_ENVIRONMENT_TYPE' ) !== false ) {
				return getenv( 'WP_ENVIRONMENT_TYPE' );
			}
			if ( getenv( 'WP_ENV' ) !== false ) {
				return getenv( 'WP_ENVIRONMENT_TYPE' );
			}
		}

		// ...
	}
