Static Shot, remove part of the background

Hello people at creative cow

I'm trying to figure out a more elegant way to remove a painting on the background of a static shot, where the acting person in the foreground is covering part of the painting from time to time.

What I learned in this forum is to build an alpha channel through superimposing a still frame of the (person-less) room with the shot (blend mode: difference, then apply threshhold) and using this luminance-only result as the source for an image mask on the actual shot (source: luminance). By this 'difference matte' the moving person is keyed an I could replace the complete background with a painting-less version.

But I think there has to be a way, where there's not the full video being harshly processed, but only the part where the picture is, right? Does anybody have another solution because my brain hurts right now..
