(I wasn't sure how to flair this I'm sorry if it's the wrong flair I'll change it if it is)

So, last year I finished the original Catherine and loved it, now I have the opportunity to either get Catherine full body for the switch or get it for the ps4. But yesterday while I was doing price comparison I saw that the the switch version is the non premium.

But after some googling, I saw that the premium seemed to come with collector's items. Is that the only difference? Or are components of the game actually different?
