What is clear in halacha is:
1. Seeing the writing, which brings all sorts of holy influence on a person.
2. Saying the passuk of Vezos Hatorah.
The Rav of the shule where I grew up always said Hashem elokaynu emes v’soraso emes before saying the pasuk of v’zos hatorah. I’ve looked in many siddurim over the years, and I’ve only seen this printed in one of them.
