Italophile is [understandably] mistaken.

The first image shows the view using the "Visual Refresh Preview/New Experience" modifications in Office.
See New Experience/Visual Refresh Preview - Microsoft Office - Microsoft 365 - Turning it On and Off.
Note that this also turns off display of your QAT by default.


It is certainly how some designers at Microsoft want it to appear.

The second image shows the [Quick] Styles Gallery as it has been in Word 2007-Word 2021 / 365 but for this "Visual Refresh Preview." Word 2007 and 2010 had the Change Styles button which has been moved to the Design tab's gallery of [Quick] Style Sets.
For a glance at the history of the Home tab in Ribbon versions, see Home Tab.
