In the following picture

without any further treatment after removing from the boards,
one has been desoldered from a lead-free soldered board and the other from
a
leaded-solder board. Particularly looking at the top pin of each capacitor
would anyone care to comment?

It was awkward getting the illumination angle right.
The top one has a "silvery" coating to the pin and the bottom one a matt,
"dusty" ie not metallic, light greyish, coating.
