I will opine that to be marketing hype and nothing more. Oil analysis will give you a snapshot in time, so unless you’ve been collecting them periodically, there is no history to be had.
A couple of additional thoughts - if you really want to understand the oil, knowing what was put in the engine at the last change is critical and the number of miles since the last change is equally critical.

Now I need to order the IMS Supplemental Toolkit from LN Engineering, necessary to install the Solution's bushing. (I've stopped calling it a bearing. It's a bushing, folks.)

Erm. It’s a bearing. Not a rolling element bearing like the one you removed, but a journal bearing. No clue of the essential details of the LN design (dimensional, pressure in the feed line, etc), so I can’t comment on the actual hydrodynamics of it all (and, in the last 35 years, I’ve forgotten pretty much all of the detail I once knew). Unlike rod and crank mains, it sees no impact loads, so a much less complex problem set in that regard.
Lots of flashbacks to closed form calculations, using tensor notation, in that Lubrication Theory elective I took as a grad student. I’m imagining any number of quality software solutions are out there today to make that a whole lot easier to iterate on - LN still had to do the engineering, but the math is less drudgery.
