Is there an elegant way to make this even closer to the bulk of the text?
To be honest, your original image is not too good. The text is without anti-aliasing, the semi-transparent edge pixels which give the impression of smoothness. One benefit is Colors -> Threshold does no damage but it does not make for a wonderful image.
I think the two lines are these, and the original text is bold, so the result is bold.
No real way of fixing that, except by totally replacing the text, using a matching font, (if you can find it)
I did have a quick look around for the original, but could not find anything. If it came from a PDF it might be editable in a PDF editor (not GIMP)
