TL;DR: That is almost correct. `:post' header arg gives fine control of 
formatting if needed.

`org-babel-insert-result' formats anything that isn't a string or a list 
using "%S". Then it tries hard to turn a list into a "table". Lists that 
cannot be made into tables are formatted as strings with "%s\n". However, 
various languages have their own formatting principles, so what 
`org-babel-insert-result' gets as the `result' is a bit idiosyncratic.

You can get a deeper look at the `result' by pretty printing it with the 
aid of a :post header arg. Example:


#+NAME: I-feel-pretty
#+BEGIN_SRC emacs-lisp :results pp
*this*
#+END_SRC

This elisp list is not revised:

#+BEGIN_SRC emacs-lisp :post I-feel-pretty
'(a b c (d . e))
#+END_SRC

#+RESULTS:
: (a b c
:    (d . e))


But R turns its list into an R data.frame and then into a elisp list with 
an element for each row:

#+BEGIN_SRC R :post I-feel-pretty
list(a="a",b="b", c="c", d=c("d", "e"))
#+END_SRC

#+RESULTS:
: (("a" "b" "c" "d")
:  ("a" "b" "c" "e"))

HTH,

Chuck
