As @lumpynose implies, the "bug" is that the device is actually rendering the book as asked. Whoever created the book decided that the contents page should have different colours for the ToC links and these are being rendered as paler greys. If you open them on a device/apps that can show colours, you will see this. The calibre viewer is a good method to see this.
As far as I can tell, the default styles used for a link on the device are simply to underline them. If there are any colours used, they are not obvious.
The fix is to fix the book. There isn't really a way to patch this as each book will use different colours or styles for these links. And knowing which are the styles to change is not really possible. At the most, the patch could set a standard style for all links, and that is probably not desirable.
