If you test your site with Google’s Structured data testing tool you will get an error about itemprop “logo” not being recognized by google as a WP Header element.
Here is how you remove itemprop

add_filter( 'get_custom_logo', 'wecodeart_com' );
// Filter the output of logo to fix Googles Error about itemprop logo
function wecodeart_com() {
	$custom_logo_id = get_theme_mod( 'custom_logo' );
	$html = sprintf( '<a href="%1$s" class="custom-logo-link" rel="home" itemprop="url">%2$s</a>',
            esc_url( home_url( '/' ) ),
            wp_get_attachment_image( $custom_logo_id, 'full', false, array(
                'class'    => 'custom-logo',
            ) )
        );
	return $html;	
}
