>>In other words... I'm still not convinced that tablets or phones are very good for "coloring" or "painting" for children.

My personal experience has shown they can be very beneficial. My little sister has Down Syndrome and never did well with regular book coloring. I downloaded an app that used tap-to-fill and what she learned from it has carried over to real life. She learned the lines are the edges for colors, different sections can be different colors, etc. I fully credit the app with teaching her that.
