No, they are different.  Look at the RGB values, if you don't see that
by just looking at the colors.  Blue3 looks sufficiently different
from black on my display.

Anyway, time to close this bug report.

Two problems related to `list-colors-display':

1. On a tty, running `M-x list-colors-display RET' displays
truncated hex color values like:              red    #cd000$
where $ is displayed at the end of the partial line.

To display the complete line this could be fixed by incrementing
`align-to' from 9 to 10 in `list-colors-print'.  But after that
when running it on X two extra spaces are displayed at the end
of these lines.

Maybe the bug is somewhere deeper in the display engine
that aligns differently on a tty and X?

2. New faces `gtk_selection_fg_color' and `gtk_selection_bg_color'
now are available for using on GTK but they are not listed in
`list-colors-display', and they can't be selected and completed in
`customize-face'.

There are more colors that are valid for using but hidden from users
such as e.g. on a tty: `unspecified-fg', `unspecified-bg'.
