Looked at several images and unboxing vids, all have it.
Suppose you could look for a delid vid to see if someone mentions what it is?
Its normal. Unfortunately the IHS is too thicc and reduces the cooling performance. Without the IHS the CPU is at least 20 - 25 degre Celsius cooler " out of the box ". I would be better happy if we can buy the CPU without the IHS or with much thinner IHS. Removing the heat spredder means we immediately losing the Warranty.
