No, not really.

What you probably refer to is the visual difference if you look at the
antialiased borders of any object (there is nothing "special" about text
objects) they look "lighter" if the alpha-channel output is on and the image
is presented on a (nearly plain) background taking the alpha channel into
account.  This is simply because both the color and the alpha channel are
antialiased and thus the resulting borders where antialiasing is used look
different.  I know this doesn't look perfect or wrong, but it is the way
antialiasing works.  Try it with a dark background and you will see the
effect change as it should...
