In summary, it appears that the look you prefer was there for a while, and now Word has returned to showing a preview above the style name.
I was surprised to see this, as I am having to use Word 365 on my laptop while my desktop is being repaired, and I'm pretty sure I hadn't performed the Registry edit to revert the "new look" on my laptop (which I rarely use and almost never in Word). I guess this is a response to the generally adverse reaction to the "new look."
Stefan and Suzanne: I am delighted to hear of this change. I did have the registry edit and have removed it.
I would have no objection to Microsoft making this optional, but really resented it.

Take a look on my article about this:
New Experience/Visual Refresh Preview - Microsoft Office - Microsoft 365 - Turning it On and Off
Is this the change you are talking about?
Here is the Home tab before the New Experience/Visual Refresh Preview.
Here it is with the New Experience.

Are we correct in guessing that you prefer the second view with fewer styles and the name formatted rather than a formatted sample with the name below? Or, are we mis-reading your question?
If you want the second view, I will experiment to see if a registry entry can give it to you.
The [Quick] Styles Gallery on the Home tab is one way to access styles, not necessarily the most useful way.There are other ways to display and use styles. Here is a link to a free Add-In that will give you options in your QAT to help with styles.
