Yes. In fact, an HDRI sky can be TO bright, leading in an image that is
over exposed like.
For that to work, you need to use radiosity.
Next, you can apply the HDRI to a sky_sphere or a very large sphere
enclosing the scene.
In the case of the world sphere, it need a finish similar to :
finish{
diffuse 0
emission 1
}
If the scene is to dark, you increase the emission value, and reduce it
if it's to bright.
