The one problem I see in creating a more muted background is the clock and mirror on the mantle.
The lighter you go the more obvious it is as to exactly what these objects are. However, the darker they get the more curiousity there will be as to just what they are. Couple that with the mirror offering the double image and it might get a little awkward in it's translation.
I'm sure the selection of this room gives some additional meaning to the portrait, therefore, you probably wouldn't want to eliminate the clock. But it is something that comes to my mind. Also, in your efforts to explain the object with sufficient light it might lead you toward more and more of a literal translation which would tend not to advance the subject.
If I had complete authority I would mute the background, still suggesting the mirror, and eliminate the clock.
It's always a puzzle, isn't it. Even with really good reference.
