CPU contact pad discoloration is not uncommon. It can happen due to age, heat exposure, or manufacturing issues. Your experience with the previous PC is relevant since similar problems have been reported. Checking if other users face the same issue might help clarify it.

If it functions, it's acceptable; if not, it's unacceptable. My prediction would be based on fingerprints or the cleaning liquid used for the CPU (such as thermal paste), because a burn would likely indicate a dead CPU.

The components are made of copper with a nickel coating, which was then coated in gold. It's likely that some areas weren't fully cleaned during the gold immersion, leading to the observed discoloration. I examined my own CPUs, focusing on older Intel models. My Core i5 3570K, which is still operational, was in good condition when I first took it out. The other model, a Core i3 3240, had seen little use and showed signs of wear. Some images were hard to interpret due to lighting, but I could still notice the dark spots on the CPU surfaces. The first one was the Core i3 3240, which appeared clean and pristine. The second was the Core i5 3570K, revealing a specific darkened spot near the center and top. It was still working despite the appearance.
