Due to the short duration of the SEQ IVA test, the tracking is broken up into smaller "tracks" along the surface of the lobe. These don't look all that hot when viewed up close, however they do represent that the lobe and roller are not perfectly flat; they are both machined surfaces, with one rolling on the other. Hence the irregularities in the tracks. The "shiny" lobe is what happens when you take a piece of fine emery cloth to the Ford cam Ben showed. The irregularities are worn down and the finish is SMOOTH. Material has been REMOVED. So while the "sweet, it's SHINY!" lobe LOOKS better, it has MORE WEAR than the factory finished lobe that has some light tracking from where the surface pressure differences between the two machined surfaces: that of the cam lobe, and that of the roller acting upon it, are the greatest.
I'd run it. Looks in good shape for an in-service roller cam.

Now, as to what value it is to us ... I'd say none whatsoever (and not calling Mobil or anyone else out; everything is more convincing with a photo than text alone, so they're going to do it because it persuades more people than if you don't).

A single photo of a single service example isn't helpful, it's just illustrative. We'd learn as much from a drawing as a photo. Think of it as an example showing whatever the text is suggesting, nothing more.

It doesn't validate nor invalidate whatever they're proposing is happening; it's just an aid to comprehension of whatever they're trying to convince you of.

Put your hand over the photo, read what they're saying. Does it make sense, or is it just marketing? You decide, then carry on. Rinse, repeat.
