The "robot as an avatar" part is something really interesting I've never thought about as yes, like most of us, the first thing that comes to mind is personal care.

But if we think about it, a true personal assistant would have a lot of wonderful uses : you would "send" your insanely beautiful looking android (beautiful can be anything, from gorgeous to super stylish), packed with a refined communication module, as a representative for all basic social tasks.

Search for a better job, negociate a better price for a furniture or acquisition, meet real estate agencies, team leading assistant at work, be a top host for your receptions at home, etc. I can already see a lot of leverage for people who either don't have the time or adequate skills for all of these.

Basically it would be the equivalent of having a multi-field personal agent doubled with a high representative value. I'm not sure I would be the target audience but there's indeed a booming market waiting to happen. And of course inducing some weird situations like android-to-android negociations, but whatever. Some people could clearly benefit a lot from it. Social exchange privileges wouldn't be reserved to attractive or overly skilled people anymore. It would be available to the masses.

Strange but interesting days ahead indeed. Also yes, I've played Detroit Become Human and really loved the questions it raised.
