The summary page will only show AV info scanned via WMI. The current status of the AV can also only be retrieved via WMI. The built-in AV reports should take this into account and will show that you have AV software installed.
If your AV software is detected with software comparison like what you have, status cannot be retrieved. You could look for this information in registry keys. Additionally, for some AV software you can also scan the definition file, and by checking the last changed date you know when it was last updated.
