Yes, you are right. It may have been like that with sandy bridge, but afaik haswell did not go full turbo speed on all cores. Same with skylake and kaby lake.
All core turbo clock is still above normal clock but not exactly the advertized turbo clock.
But yeah all this doesn't matter much since any Intel CPU to date with advertized single core turbo almost reaches to that turbo clocks on all cores with manual overclocking. It is safe to say that CL i7-8700k
overclock should reach at least 4.3GHz on all cores(if single core turbo is 4.3GHz). i7-8700 might not reach 4.3 GHz on all cores on its own.
