That's exquisite. That took some time.
I can see the blowout. When you're working with wood that thin if the screw ends exert any pressure at all against the fibers at the end of the hole it will create a very noticeable bulge on the opposite face. I assume they didn't "blow out" but that they bulged and in trying to sand down the bulge you exposed the screw holes?
Whether it happened that way or not, your post-finish fix is to fabricate vary small plugs. Use the same Purpleheart you used for the inlays and B'flies and it will look fantastic. It won't look like a "fix", it'll accentuate even more. It's a beautiful piece and it deserves that one last effort. JMHO.
Edit: I just reread this and I think I should clarify that in this case, they wouldn't be "hole plugs" because you do not have a hole, but the same principle applies - they will be "caps". That actually makes it even easier. Let me know if I'm not painting a clear picture but this is an easy fix.
