On run in most of the metal would be coming from the gearbox. Personally I think the change at 100km was a bit of a overkill maybe 500km for the first, but it is hard to go past your pictures of the filters stacked up against each other. Would have been interesting to have the oils analysed at the 100km, 200km and 500km oil changes to see contaminates in the oil. I do agree with Kev in saying that mineral oil should have been used in the run in period. Another note would be the run in period would vary dependent on the individual person and bike.
