Unfortunately at least for me this procedure did not work. Even my XPS 15-9570 has the problem of saturated colors from BIOS 1.6 and it amazes me that Dell still hasn't fixed it. Even today with BIOS 1.8.1 the same situation. I try to fix it by setting the saturation to -22 in the Intel Graphics Control Panel, but I'm very upset about it. Moreover, "PremierColor" no longer works. It starts but the changes have no effect.
Started your own thread. Before we can begin to troubleshoot:
* Click my name and private message me the XPS 15-9570 service tag number
* What operating system are you running?
* What version of Dell Premiere Color is currently installed?
