Given the interest in photo-realism a disclaimer might be in order. This is the first shot in a animation for the family and photo - realism is not even a consideration. Hell for that matter I’m not using Filmic because saturated color is the order of the day.
The lighting in the place is area lights with mesh lights for the camera and what you see in the overhead is the actual lighting. And, when I move the camera inside and lower the value of either it is obvious. But, not so outside here where the lighting is coming through glass. Regardless of the value set on the interior lights what you see in the glass does not change.
And, I suspect I have changed every setting known to a Blenderhead and tried every glass material YouTube has to offer with the same results. The brightness / intensity of what is seen in the glass does not change. Regardless of what level the interior lights are set to.
