Is a Front-of-package Label Contaning Information on Both Nutrient Profile and Ultra-processing Well Understood?

"Participants in the experimental arm can see, in case the product is ultra-processed, a black banner surrounding the Nutri-Score, with the word ultra-transformé, meaning ultra-processed, and no black banner otherwise. Participants in the control arm had no label at all. The intervention (the Nutri-Score 2.0) was added on the packaging on the products included in the 3 sets of images that participants recieved via the questionnaire."
