Icicles has done this since 2007.  See here:

https://www.emacswiki.org/emacs/Icicles_-_Candidates_with_Text_Properties

(FWIW, I see this Note on that page:
   "2007-01-24 - RMS has agreed to fix Emacs in this
    way, so this will become possible in Emacs."
 AFAIK, that never happened.)

Whether face, color, etc. completion candidates are
shown as, or accompanied by, such propertized samples is
controlled by option `icicle-WYSIWYG-Completions-flag':

---8<-------

icicle-WYSIWYG-Completions-flag is a variable defined in `icicles-opt.el'.

Its value is "MMMM"

Documentation:
Non-nil means show candidates in `*Completions*' using WYSIWYG.
This has an effect only for completion of things like faces, fonts,
and colors.

For face and color candidates, the particular non-nil value determines
the appearance:

* If t, the candidate displays its meaning: WYSIWYG.
* If a string, the string is propertized and then appended to the
  candidate,  to serve as a color swatch.

Some commands might override a string value with different text.  This
is the case for `icicle-read-color-WYSIWYG', for instance: the color
swatch text is always the color's RGB code.

Note that, starting with Emacs 22, if this option is non-nil, then
command `describe-face' does not use `completing-read-multiple', since
that (non-Icicles) function does not support WYSIWYG candidates.
