Here are the two UOA's performed with Mobil 1 5W-30. I've now moved on in my oil sampling with this car to Redline 5W-30.
Important note about the fuel dilution results: 1st sample (1st 5K oci) was done with a short warm-up before drain - 3.8% fuel dilution on a new engine!; 2nd sample (2nd 5K oci) was done after 20 minutes of driving, so the engine had been fully warmed before draining. I found similar variations in fuel dilution with my previous Audi 2.0T (1st generation DI with timing belt).

Blackstone summary comments:
Sample 1: Typ wear levels for new engine
Steady wear metals
High Al, Cu, Si likely residual wear
3.8% fuel dilution is cautionary
Sample 2: Fuel dilution has disappeared
Al is OK, Cu is normal
Visc dropped to 5W-20
