Am I missing comething? Seems like there's no "before" picture or video, just the "after". Having both would be far more useful, because we lack an objective method to see if anything happened otherwise.

Someplace on here we have reports indicating that Redline (May have been the old redline before they got bought out) made claims that some constituents survived combustion and could clean the valve system through the PCV. I find that dubious for emissions reasons, but am happy to be wrong.
Others now do sell purpose-specific DI cleaner, very carefully worded to imply it cleans the system, but stops before claiming it can clean the valves. I have to wonder how much deposit ends up on any modern injector...
