Virgin silicon numbers for redline are about 16-18ppm (anti-foam additive) and very often we see it in the 6-11ppm range on UOAs. So no worries there.
Likewise for lead, previous UOAs showed 2-3 and a change to 4 is no big deal and may be within "noise" levels. Now if in the future you see a continuing upward trend, that would be different.
It would be interesting to see how straight RL 5w40 would do in this engine. Your UOA shows pretty amazing viscosity retention for this engine which chews up PAO-based 502 oils.
FYI here is a related post regarding shearing of a popular 502 oil:

I am not saying anything good or bad about this oil, but Pablo's statement about shearing is accurate IMO, at least for this engine.
