They now all look the same, but for some reason they look almost
white, not black.

I cannot reproduce this on systems to which I have access, so you or
someone else will have to debug this with that particular terminal.

What does the below report on that terminal?

  M-: (tty-color-desc "#000000000000") RET

What do you mean by "dark theme"?  This is in "emacs -Q", right?
without any theme being loaded by Emacs, right?
