Lol! I'm sorry I didn't laugh earlier.
I tried many clients but couldn't see your username in any.
Can you see it if you use a web client and search for your own npub? 

 In amethyst, you can click your profile picture on the top left, then choose to see your profile.
On your profile page, to the left of the follow button, there is the button to edit your profile.
You can try to edit your display name, maybe it was not transmitted to the relays when you did. 

 Didn't work. My profile popped up on snort.social when I searched "scoundrel", but going to my profile directly does not display it. 

 Now I can see your name, but no profile pic  

 I didn't have a profile picture until just now, so that's not an issue.
