It makes a lot of sense, though - interior decorations change (with very few exceptions, e.g. the French communist party HQ, which came pre-equipped with Niemeyer-designed furniture). Light impressions don't and have a lot of practical and emotional effect on how space is used.
I would say there's value in having both kinds of renders - one which focuses on the architecture itself and one which paints a vision of how it might be used. If it isn't too distracting, you could switch back and forth between the two during an animation.
