Google is busy these days, redesigning App but now the new Material Design comes slowly on the web results.
Google Search got changed like color to the tabs of the knowledge graph, which now have the header with solid background (basically in agreement with the color of the pictures shown above). The expand card button got circular, and also in colored.
It has few small Material Design elements but do not expect special animations, since it is still a service via the web. We also point out that it is not yet available to everyone, but we think that at this point it is just a matter of having to wait for a wider roll-out. Source : Androidworld
