Again, that's the case now because per-core CPU performance has been stagnant for the past four years. Going back even further, improvements in per-core CPU perf have really tapered off after Sandy Bridge launched in early 2011.

Buying a faster PC for its performance isn't worth it when faster is like 10% faster.

The comparison with 4K TVs doesn't make sense.
4K TVs: significantly more resolution is available, but there's not much content for it, and/or people don't have the internet bandwidth to stream it
CPUs: significantly more per-core perf is not available if you have anything later than Sandy Bridge

In contrast, there are plenty of tasks that'll benefit from more per-core CPU power. Let's start with gaming - can we agree at least gaming is a pretty big market? If we get a much better desktop CPU, I bet there will be a ton of people upgrading from Sandy Bridge.
