Honestly, I think you're putting too much thought into it. It's meant to be fun and relaxing. I don't see the harm in trying it if you want; and anything to get a child away from a device I say is worth it. No, it's not "art therapy", but it can be therapeutic and some professionals may suggest it to someone to try, but every professional has to be extremely careful when describing what they do and don't do. Most non-art professional therapists who do this would not call it art therapy. There are a lot of twisted truths and blatant lies in the marketing of pretty much everything anyway.

I love the "stained glass" ones which are basically translucent pages, but I use markers and end up making a mess. I'm not sure what else would work on them though. It's actually a lot cheaper to get the ones for kids. The industry has realized they can make money on it and have taken advantage.
