Clearly not. A person posting a picture is performing an explicit act of sharing a specific piece of content. Even in the case where the person doesn't know what that entails, they have made a choice to share specific content. With smart TVs it will be unclear to the person that recording is even happening, much less how that data is used and for what purpose - so the likelihood of them realizing that data is being shared or that they need to show consideration for how data about others in presence of the TV is shared will be close to nil.
