What I do know is, with over 200K on our direct injection Honda turbo civic , we have not had to take it apart for intake valve cleaning which has been a HUGE issue for all direct engines.
Direct injection engines accumulate a huge build-up on the back side of the valves, making them run terribly.
So far so good.
I use 100% synthetic oil afaik.

They had 2 identical Ford Explorers running 2.3L turbo 4-cyl. One engine ran Valvoline synthetic oil, the other engine ran valvoline conventional oil. The motors ran with computer controlled throttle that varied the motors through various rpm in some pattern for 500,000 miles. The oil was checked every 8 hours. Both motors had "normal" mechanical issues that were repaired as needed.

It was a comparison of 2 identical motors run in the same way in the same place using 2 different oils. They either both had direct injection or they both didn't have direct injection. When comparing 2 identical motors that ran dissimilar oils, what difference does it make if they were both DI or not?

No, they didn't measure anything. I suspect Valvoline is going to do that sort of in-depth analysis of the motors, essentially blueprinting the engines to compare details. This was a quick video showing visual difference. I suspect it was essentially a commercial meant to get folks to buy valvoline synthetic oil.
