You have a 7.1 bed system, configure it as such.
Maybe experiment with moving those side speakers to by the endtable, same across from the fireplace, and if possible the rear speakers a little further back behind the couch.
You can never get any height information from a bed level and aimed speaker. Sending Atmos elevation information to bed level speakers like that can only serve to blur both the Atmos objects and the bed level channel positions.
If you insist, at least see if you can find a way to point the side (Atmos) speakers at the ceiling to attempt to get some bounce, but not recommended. JMHO
