Tbf a lot of famous artists from the Renaissance on had apprentices and often did only bits and pieces of the actual painting (although they'd have supplied the design, ofc, and directed the apprentices painting it).
I watched this lately, on Amazon Prime maybe, and it thoroughly depressed me about the entanglement of art and finance. Tale as old as time, I suppose, but whereas religious art, for example, was valued for its creation of a spectacle which would amaze and transport ordinary people (or other people anyway) - as propaganda for the church, but necessarily capitalising and drawing on real emotions - the modern art which billionaires snap up often seems more like a cheap trick, designed to tickle somebody's sense of irony and then furnish a skyscraper lobby.
This isn't the artists fault or intention. More reflective of the sort of rather shallow and inane "meaning" which the billionaire class can very comfortably live with.
