All the flecks in the photos and video you posted look to me look like the bits that appeared in my Leica v4 35 Summicron. They might be anodisation, paint, or dust. Once I had my lens apart and I looked at the blades with a dissecting microscope, I could find shapes that were uncoated/unpainted that corresponded to some of the flecks. Others not so much. I don’t know if it is paint or a chemical coating like anodisation, or how much is dust. From the lenses I have bought brand new, I do know Leica lenses come (usually very lightly) pre-dusted.
Oil on the blades is only a problem when it gums up instant return apertures on SLR lenses. Oil is not really a problem on rangefinder lenses. The vast majority of lenses have some to a lot of dust in them.
Either get over it and use the lens (I never have had a problem from it and I got my v4 in 1998) or sell it. Worrying about photos of the lens, as opposed to photos taken with it, is pointless.
