Yes, I mentioned it in my mail:

But customize use a different implementation, not read-color (at least on 27)
and other commands do not use read-color at all, despite getting color input,
they just list the color names without coloring them.

Other commands which read a face, not a color, show just face names for
completion. Showing face colors and other attributes inline (like in case
of list-faces-display) could be a nice improvement.
