I wouldn't say bullshit. Diminishing returns should be expected, even in embarrassingly parallel workloads, because of Amdahl's law as well as physical limitations regarding power delivery and cooling when utilizing all the cores.
That said, I like your "real cores" metric. Looking at $/"real core" would be very informative. But even then, there's still folks for whom the time saved would be worth the price premium.
Also, I'm not sure about Geekbench's MC score when run on TR. They've had problems in the past.
If I run your bullshit factor analysis with the i7-8086K vs the Ryzen 9 3950X using the single-core and 64-core workload tests from User Benchmark (no 3rd gen Threadrippers there yet) both get a bullshit factor of about 155%. Even the Threadripper 2990WX only has a bs factor of about 192%.
