No, lumpsucker is showing the same failure on 9.5 as well.  I suspect
that the reason 9.6 and up are OK is that 9.6 is where we introduced
the abbreviated-sort-key machinery.  IOW, the problem exists in the
old-style UUID sort comparator but not the new one.  Which is pretty
darn odd, because the old-style comparator is just memcmp().  How
could that be broken without causing lots more issues?
