This is what HDR does as per definition. It transforms both colors and brightness to a higher range than standard, so whites will look more blown out and colors more saturated. There still seems to be big misconceptions regarding this. This image is an early wip screenshot, but it demonstrates quite well what HDR does. It does affect everything, from colors to darkness of shadows. If ISI would change it now, they would probably need to re-tweak every texture of every existing track, as all textures are now tuned to work with current system.
