Is my alternator on its way out or have I never noticed before?

Battery gauge on cluster dips to half then comes back up to about 5/8s on the gauge. No warning lights or CELs appear.

I've checked through all settings for a digital voltage output but nothing.

I've seen smaller fluctuating with smaller loads like closing the windows.

I can see the gauge doing this if it's an ammeter but not a voltmeter.

Battery is only 6 months old German made AGM.
