Why is that? If your system supports display of SVG images, why wasn't the text readable?

It is only non-nil if your Emacs supports display of SVG images, and in that case I don't see why not do it. I think we should investigate your problem in more detail to understand why it didn't work for you. I hope Tassilo will have some ideas for looking into this.
