In a focused experience video, you can never cover all aspects of a library. For that you'd need to compose pieces in various genres, go ham with the deep editing options that the library features and do a review after perhaps half a year to really have mastered it.
Those content creators who do 2-3 hour streams even can't even explain all facets of the library. Even though, 2 or 3 times I mentioned CSS, I'd assume 90% of the video are about TSS, and TSS alone. Personally, I think a catch-phrase is good for grabbing attention, but shouldn't be taken too seriously
Another content creator from a different background might compare it to another Impact Soundworks product from a technical standpoint (the evolution of the TACT engine etc.). And it will be also valid, but also very selective and not paint a *complete* picture.
A content creator from Japan might give other insights yet again. Someone
compared it to LA scoring strings for example. With all these perspectives and slices of insight, one can build a more complete picture themselves. For entertainment purposes, education, or as a purchase decision.
