Retouched screencaps (these are very large PNGs):
The “White Outline” dinosaur products are real, off-the-shelf merchandise (but not JP-licensed), occasionally with a JP sticker slapped on them. The stuffed dinos are real, off-the-shelf stuffed animals, but not from JP. The lunch boxes appear to be blanks with a JP sticker on them. The book is based on the real making of book, but likely with a mocked-up cover. The large size and proportions seem correct. The real book is approx. 8.75 x 11 x 0.5 inches. The authors are Shay and Duncan.
I suspect the shirts are real JP merch, as they have the copyright / trademark disclaimer text inside the bottom of the yellow border of the JP logo. The Jeep door graphics, for example, do not have this.
