Everything I have seen on Magnatec shows good UOA's. I have no clue if it works or does anything speical, but it shows good wear results and that is what is important.
A serious question about magnatec

That's the question though; is everything just sticking to the inside of the engine and not draining out with the rest of the oil to be analyzed? Is that something that can actually happen?

Where was you read that?
I have never seen Castrol make any official claims about that.
But i would not be surprised if that was true since there is still some amount of oil left in the engine after the oil have been drained.
So i guess its a statment that is also valid for most engine oils since there is always some oil left behind from the previous oilchange.
If you run Redline oil as example and then switch to Mobil im quite sure you will be able to detect molekules from the Redline oil on the engine surfaces, Nothing strange with that.
Castrol has actually publicly stated they use esters in their oil to cling to parts for well over 20 years. Do a google search and you will find multiple examples of this. The advertising for Magnatec is simply a new angle on something that has been in their formulations for decades.

And the same can be said about 95% oils out there.
Typically when a UOA looks bad (what does that actually mean?) it's because of some issue with an engine and not necessarily an indicator that an oil is bad.

Isn't that true of any oil, and why it is recommended when changing brands and doing a UOA with the new oil to do it on the second run?

^ This !!
The oil is in constant flow with the engine on, it doesn't just sit there.

I have never seen Castrol make any official claims about that.
When I was buying 10s of thousands of gallons of turbine oil at a time, I was invited to a dinner with Castrol, a racing driver, and had the fortune to sit next to one of their chemists, and we spoke at length about the "new" Magnatec.
He stated that in their engine test programme, they used theri baseline oil (M1 5W50 at the time), then flushing oil, the test oil (Magnatec), flushing oil, then their reference oil again to rule out engine related changes that could affect the results.
He stated that the effect of the Castrol UMA additive could be seen in the flushing oil, AND the reference test.

Thanks Shannow, I was hoping you would answer this question. Just to make it more obvious ( and please correct me if I got this wrong) the effects of the UMA additive lasted through the flushing phase, and could still be measured (in a positive way) in the end reference M1 5W-50 test even after the flush.
This is consistent with what I have heard before. Yes all oils cling to metal surfaces to some degree, but Castrol have put special effort into developing an additive that does this much better than regular oils, in a way that can be measured and quantified in test rigs. It's the real deal, but yes the marketing is trite. Blame that on the marketing people, not the chemists.
BTW Magnatec has been in Australia for many decades and is well respected here. It certainly did use esters in the old days, but I suspect the chemistry has been updated since then.

Not saying that this is Magnatec...just saying the phenomenon has been researched, tested, and proven.

Piston ring wear measurements were carried out in a standard production 2.3-liter engine using compression rings that had been subjected to bulk thermal neutron bombardment. As the radioisotopes produced by this process were worn from the rings during each test run, they served as irradiated tracers for the detection of wear particles.
A total of 32 tests were conducted on six different oils. All oils showed two distinct types of wear. The first, start-up wear, is characterized by a high wear rate and a relatively short duration. The second, steady-state wear, showed a much lower wear rate and continued in a constant manner for the remainder of the test. The start-up ring wear rate was substantially larger than the steady-state wear rate.
The addition of a unique boundary chemistry engine treatment substantially reduced both the total amount of piston ring wear, and the rate at which wear particles were produced during start-up.
