Rift S Display Color & Brightness configurable ?

I just got myself an Rift S and I think compared to the original Rift all Apps/Games look more non saturated and over exposed. e.g. in Space Junkies the whites/highlights are really blown out. Is there a way to configure the display settings on Rift S globally for all applications via Oculus software or openvr ?

I was quite happy with the old Rift an liked its display and sound...the Rift S seems more a downgrade for me at this time...but maybe it is just a little bit to early to judge this.

thanks for any tip.
