How to update WordPress via wp-cli without output messages?

I have a cronjob that updates my WP sites every night via wp-cli. I want to be informed about errors (and only errors) during the update process via mail. So I use the parameter --quiet which suppresses „informational messages“:

wp plugin update --all --quiet

However if a plugin is updated wp-cli still outputs a message like:

+------------+-------------+-------------+---------+
| name       | old_version | new_version | status  |
+------------+-------------+-------------+---------+
| insert-php | 2.0.2       | 2.0.4       | Updated |
+------------+-------------+-------------+---------+

(How) Can I suppress those messages too?

Regards,
Stefan
