Again, pointing out that several tests from multiple users (including a long Gearslutz thread containing Logic project to test RTP) and a Sound On Sound article, etc, disproves the theory that multiple cores does not increases RTP. This is especially true for script heavy Kontakt patches that uses multi-core processing to handle non-audio related instructions. Also, this video is even less actual today when plugin and DAW manufacturers have optimized their software for multicore use.
Would Apple and all specialized PC DAW Building companies lie about this without anyone discovering it? No.
Are there other factors that can affect RTP? Yes, there is. But disregarding those, multiple cores significantly increases Real Time Performance as long as the system doesn't have any other problems.
I linked the SOS article several years ago:
Some music applications will completely fail to take advantage of the multiple cores of a modern CPU — but which ones, and why? We find out, and advise on how you can make best use of however many cores your PC has.

Also this, a mix between old and new stats:

Test are conclusive.
Also, as several other in this thread has pointed out: This video has nothing to do with OSX. I did an extensive test with Mainstage when programming sounds for a musical theatre show last year, that concluded that Kontakt inside Mainstage (running single core because of multi-core utilization conflicts between Mainstage and Kontakt) increased CPU usage by double rather than running Kontakt in multi core outside Mainstage. With the exact same patches. This also disproves the "multi core doesn't affect performance theory, and Mainstage is very realtime sensitive since it's live playback. This was confirmed on 4 different systems.
I don't agree with the conclusion of this video, and there are plenty of sources to back that up. I can't say what the video author's specific template does for this theory, but in all my cases of building orchestral setups throughout the years, there simply one conclusion:
More Cores = Better Performance.
