Unless it is just the lighting, the 3rd photo seems to show some slight discoloration on the race. A straw color. This would indicate heat, possibly from running too tight. Also appears to either have grease streaks or the beginning signs of brinneling.
Even with a unitized bearing assembly, one meant to be torqued into place, there should be a slight amount of axial play in the assembled wheel hub. Approximately .001-.003".
