Using different number of colors on different ttys should work.
I just tried it briefly, and it works fine on my Fedora machine with
24.5.
I don't have a very recent version compiled.
You can try it with
$ emacs -Q -f server-start&
Then from an xterm: emacsclient -t
And then from a different one: env TERM=vt100 emacsclient -t
The frame in the first xterm should display some colors, the one in the
second should be b&w...
