besides the camera issue…with renderings you have to be very careful using white…common mistake is white is 255,255,255 but should be close to 200 and i think you are using high values…this is why looks burn closet to the window and no much contrast between shadows and lights.
I would use LC/QMC for GI and the subdivisions are extremly high…I wouldn’t go over 24…maybve between 12/16 would be ok
