The heatsink's base is flat but has a lot of milling marks. On the photos you can clearly see how the base is composed of all the small copper fins joined together in the center.
A bit further out near the edges the surface is quite rough, but this is not a problem since the CPU will not need heat transfer there. In modern processors all heat is generated in the tiny die right in the middle, under the heatspreader.
