The preferences are stored somewhere in .TeXmacs (need
to grep them to know exactly where and how a given default
value is stored).

One could imagine that the preferences in the .TeXmacs are
initialized during the install, although I don't think it
is the case.

Usually, default values are stored in env_default.cpp, but
for the paper size, it cannot be, for it is :
[[
env (PAGE_TYPE)= "a4";
]]

, and as you said, the real value is "letter", thus it is
overriden later.

Bingo (tm-print.scm) :
[[
(tm-define (get-default-paper-size)
 (or (getenv "PAPERSIZE")
     (let ((papersizefile (or (getenv "PAPERCONF") '"/etc/papersize")))
       (if
        (access? papersizefile R_OK)
        (let ((pps-port (open-input-file papersizefile)))
          (let ((size (read-line pps-port)))
            (begin
              (close-input-port pps-port)
              size)))
        "a4"))))
