The HDRI Cloudy Skies are calibrated for the default Iray Render Settings, most materials will react very well, only minor adjustments might be necessary like adjusting the "Base Color" and "Glossy color" to white (back to the Iray defaults) will be the best option in the majority of cases, this will give the exact color of the Texture in the Surfaces.

This product contains 12 HDRI´s at 16k x 8k pixels and a preview size at 1K X 0.5k. To light without sharp reflections or background one can use the preview size at 1K it loads faster also provides a better workflow and the light is very similar. One can load the HDRI´s from the Render Presets, or directly from the Textures folder in the Runtime Libraries, quick note, set the folder for "Large Icons" so you can see the thumbnails of the HDR and Mat.
