I was expecting to see some M- appear. In fact my idea was that if
there is no IFS splitting happening, it's because indeed there are no
IFS characters in there: the spaces have actually their 8bit set.
But maybe the quotes used in the echo reestablish the 8th bit? Maybe
default="a b c"
: ${list1=$default}
: ${list2="$default"}
echo $list1 | cat -v
echo $list2 | cat -v
demonstrates it? Or maybe it is `cat -v' that doesn't and od should
be used.

Yes, sorry, that was a typo.
