Linut,
You won't think you're getting anything from the photoreading step, especially as a beginner.
All the information available to you on a conscious level will be from those steps, yes.
After you photoread a lot, you will strengthen the gap between the conscious and non conscious mind and will be able to get information you want after just a photoread.
The blip page is nothing to worry about, just don't focus on the words, and make sure the whole book is in your view, so that you can see the center and all the four corners of the book.
The mixed text is fine, you shouldn't even be thinking about this while hotoreading. Just focus on the chant, and trust that you're taking in the information.
