I watched the first four minutes, past where she talks about the "challenge"/reprofile. It sounds like she kept touching up the factory edge, then finally did a full reprofile, and post reprofile it's doing better. Nothing about that is magical, and it's hard to know what really went on without some more detail about what happened.
Considering the CRK edge is slightly convex, it wouldn't surprise me if the touchup sharpenings were a system for a regular v shape (since most are), and that wasn't doing well. Then she did the full reprofile that removed the convex edge, and her sharpening and touchups did better from that on. Ultimately it seems like maintenance sharpenings on the initial edge weren't doing well, she reprofile it fully, and it was good from then on out. Nothing particular to CRK or S35vn about that improving an edge. Maybe I missed something(?)

Since CRK’s come with a slight convex edge, like

said, it’s better to reprofile the edge from the get go, than to touch up the edge and complain how it doesn’t hold an edge very long. Personally, I wouldn’t take it down to 17 degrees. I try to keep the factory edge angle and do a micro bevel of a couple of degrees to know I’m hitting the apex. When I do plumbing work, I’ve realized that I put lateral stress on the edge and having the steel behind the edge reduces the steel from chipping. Typically, I know when it’s time to tou up the edge when it doesn’t cut through cardboard cleanly.

A more acute apex will give better edge holding on CRKs in my experience. I don't think that 15 degrees is necessary or optimal in most cases. 16-18 degrees is usually what I reprofile to on most models. Usually I start by by bringing the angle back to 18 degrees per side and then drop the angle lower incrementally on subsequent sharpenings whenever they end up being needed. You can always take steel out of a blade, you can never put it back in.
It is worth noting that the person in the video (and I've followed all her videos on this through IG) has done her sharpening freehand and doesn't say what kind of stones she's using, so question marks should surround any conclusions drawn from them.
Honestly, unless the person is some kind of master freehand sharpener (and they can do amazing work, don't get me wrong), I am super skeptical of the results that beginner sharpeners get while working freehand, as any kind of reliable information about the steel in the knife being sharpened. Sharpening freehand is, frankly, super imprecise and full of chances to screw up (again, unless you are some kind of master freehand sharpener, all of whom I feverishly admire).
I find that using diamond stones and using a fixed angle system like the Wicked Edge (accept no substitutes) helps to provide much more consistency for the average sharpener and user and helps far more in providing information about "how good" a steel actually performs.
