I think it's called anticipation, and i recall faintly there was a similar discussion for Axel's appartment and Louises room when those backgrounds were revealed. Some people like to sometimes use their upper head and not only the lower one.
Anyway, i am doubling down on my bet: this is Ed&Mollys livingroom.
a) The sheer size of this small room points to not being occupied by particular well-off couple, thus excluding for instance Perry's parents.
b) The only two photographs in the cabinet depict a solo shoot of a woman and a shoot of a couple in front of a landscape. These are from a childless couple, else they would have at least one family picture.
c) The whole room screams late 70s or early 80s, the wooden wall panels, the huge central cabinet featuring the TV as its centerpiece and the presence of a swiss-cheese plant (monstera deliciosa) which were a common sight back then. Although all this features get a kind of revival at the moment, this is not a livingroom of a interior design affine fashionista or hipster.
d) crowding such a small room with two additional pieces of furniture, namely the rocking chair and the foot rest means they serve a purpose. And since the chair doesn't face the TV it's not for relaxation and recreation, but for resting and sleeping, which points again to an easily exhausted, probably sickly person.
I would expect most parents in this game to be in their late 40s or max late 50s, which would make them probably too young to sport an original 70s / early 80s interior design setup for their livingrooms. They would rather go for a 90s+ style livingroom.
Here are some links if someone is interested in a more modern interpretation of that look:
