Great info! I had my bearings replaced around 50k miles and they looked very similar to yours, although I was driving the car at the track occasionally. I was always diligent about oil changes and engine warm up.
Interestingly enough, my car now has around 95k miles (but 75k miles on the replacement engine and 35k miles on the set of VAC coated bearings), and I am showing elevated copper with no increase in lead. I don't know the composition of the other engine bearings, but I imagine it is now either the camshaft, small end connecting rod, or main bearings that are wearing. This is assuming the VAC bearings are still lead over copper, just with an additional coating.
