bug#22154: 25.0.50; emacsclient -c "breaks" 256-color display in server

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.

It could also be tty-color-alist.  Can you tell me what's in it after
Emacs starts on a 256-color xterm, and after the client frame is
created?  Also, does xterm.el initialization get called for the client
frame, and does it modify tty-color-alist?
