People off to one side can still get better clarity than with a center channel that's sub-optimally placed (like most are) in terms of wall/floor/ceiling and other object proximity.
The phantom image just won't be centered except where directional speakers (wave guides, acoustically small dipoles) are configured for reduced output from the nearer speaker for off-axis listeners.
