Couple of things:
What 'matters' is that wear metals are low, not really the viscosity. Yes, low viscosity can increase wear metals, but if it doesn't, it isn't an issue. Lots of the new DI and DI/turbo cars reduce a 20-weight into 10-weight range, and wear metals are still fine. Your UOA appears to be okay wear-wise, so I wouldn't panic or necessarily stop using M1 0W-40 as it is a great oil.
Not that it is off the charts, but your silicon seems a bit high, might want to check your air filter. That can increase wear metals.
