Among results on those pages for recent items: “ARTHUR DER GROSSE“, “AIR - DER GROSSE WURF“, “DER GROßE WADAS“, “DER GROSSE GOPNIK“, “DAS GROSSE BUCH DER GUTEN GEDANKEN“, “DER GROSSE SOMMER“, “DER GROSSE YOUTUBER-BEEF“, “DAS GROSSE BUCH DER SELBST REFLEXION“, “DER GROSSE SCHLEIMFILM“, “ALEXANDER DER GROSSE“, 2x “DER GROSSE GATSBY“

You searched a digital database that will be displayed on user
screens, some of which may not have been updated for years and might
not have new fonts, and who knows when all the bibliographic systems
have been updated. Using cutting edge Unicode characters is not always
the best way. I wouldn't be surprised if there weren't systems that
still used ISO-8859-1 or MARC-8 (a library-specific tailoring of
ISO-2022) in the bibliographic loop.

On the first page of searches for me, I see 14 items; looking at
titles on cover pictures, two of which are lowercase and one of which,
"Der große Wadas", uses a ẞ on the cover. Searching Books for Der
große Gatsby shows 12 or 13 distinct covers, 6 with DER (or Der)
GROSSE GATSBY on the cover, three with DER (or Der) GROẞE GATSBY, and
4 with lowercase titles. A few dated back to 2006, so it's not a
trivial sample of modern covers.

Amazon's pretty bad for this in some ways, but judging from those
searches and a couple others, there's some use on book covers, maybe
10-15% of uppercase titles.
