Diffuse color can't be multplied above 100% and no HDRI textures at 1.5?

Yes, I used a HDRI env only.

If you want full reflection on the model, what you can do is use the HDRI on the Environment background slot and make the dome light invisible.

Ok, I managed to use domelight with hdri (nothing in env.) and to avoid the thin overlay that sucks the alpha. Simply set a black TexAcolor as GI for the base material (the one set in wrapped material). Unfortunately it brings unwanted marks but increasing settings for IM helps (see attached image). It is still not 100% perfect but acceptable. Hope it can be improved ps. subdivisions for dome light does not help but I keep it 32
