Being so young, there's break-in residual still left, but it is clearly coming down. Don't worry about the Cu; it's from the oil cooler and will settle once fully oxidized - it will chelate until it's fully seasoned.
I can tell you that, at a very minimum, you should follow the IOLM. If you are intent on continuing UOAs, then let them be your OCI guide. It is typical for a Dmax to have low wear rates, and actually continue the downward trend of wear out to 15k mile OFCIs. I have seen no distinguishable differences in wear rates from any of the 5 gens of Dmax; from LB7 to the L5P, they all wear about the same (which is to say excellent).
The very few poor Dmax UOAs I've ever seen have been from massively abused or altered engines; not unlike the guy recently whom put a improper CAT filter on (having no BP feature) and then thickening his oil to a 50 grade with Lucas; that didn't end well in the wear category ...
Just run a 10w-30 or 15w-40 HDEO conventional oil and follow the IOLM (or further); it'll be fine. Nearly 600 UOAs cannot be wrong; that's how many I have for the Dmax series of engines. Data don't lie.
