I think they would, but I'm not sure either. It seems logical that those pores are a lot larger than 4K grit particles, so you would feel all the indentations as roughness. I don't think I could tell the difference between a 4K hone and a 5K hone by touch if both had flawless surfaces.
There's been a lot of discussion about barber hones and how difficult it is to tell the grit size by the way the hone feels, and I tend to think that would extend to this instance.
It does seem, based on this limited sample, that there is a difference between the pre- and post-move hones. I'd be curious to know what causes the voids or indentations in the first place. :hmmm
