The poppy didn’t make it into the main logo. Instead it’s underneath.
I don’t believe I’ve seen Google mark a special day in this way before: with the image under the search bar.
The poppy isn’t linked to anything. When you click on it, you don’t get taken to a Google search that explains it the way you are when Google marks an event within the logo.

Presumably Google doesn’t want to err on the side of being glib about this day. They usually take a pretty whimsical approach to commemorating special events and holidays. I wonder if they’ve done something similar with other sombre special occasions, or, if not, if they’ve gotten flack for doing so.
