Hi Hort
I did some colourations of the sol 52 OMs and got some colours looking essentially like yours, without having seen yours.
I've circled what I think might be spots of interest for an AFM examination. However, there are probably many other spots that are obscured by the background noise in the images.
I suspect we will have to await the officially processed images.
Anyhow, fwiw, here are my preliminary processed images
