Why "npub:1abc..." instead of "npub1abc...", if I may ask?
Discussion
In working on these screens I just found it easier to read; kind of lets your eye just skip the prefix, BUT the prefix is still there to make it clear that these are `npub`s.
Without the colon it takes just an extra beat to find the starting point that matters.
You could use different colours to shade out "npub" string, too.
