About furniture photography, what is the lighting method of this photo?

I think the main light is a natural light reflecting umbrella, so we can consider the whole supplementary light. Low light is the fill light under the bookshelf, which is the reason why the windows don't fall to the ground and the ceiling hits from top to bottom. The highlight near the window is 45 degrees, with a theme and texture. This kind of fill light is very good for photographers and professional furniture photographers, but not all furniture can be like this, especially those with high reflective paint. Besides, these professional studios are all white-roofed.
