From my perspective, the answer is no. Because, as TheDucks mentions, the cover browser is animated, has the unnecessary reflection and only shows a single book at a time.
However, the cover browser does provide a "bare minimum" equivalent to the idea. Just consider how annoying, time consuming and wearying it would be to try and search through a calibre library of a thousand books, one cover at a time.
And many calibre users have libraries far larger than 1,000 books.
