[Message part 1 (text/plain, inline)]

I assume you meant `tty-color-mode-alist'.  After running `emacs -Q' with
TERM set to `xterm-256color`, I see

tty-color-mode-alist is a variable defined in ‘tty-colors.el’.
Its value is ((never . -1)
 (no . -1)
 (default . 0)
 (auto . 0)
 (ansi8 . 8)
 (always . 8)
 (yes . 8))

After the client frame is created, it's the same.

`terminal-init-xterm` does indeed run when I create the client frame, but
as you can see, it doesn't modify tty-color-mode-alist.
