Can’t change color profiles

Hi, I have an iMac 5K 2017 running the latest version of macOS Catalina.

After some troubleshooting I had with an Apple’s advisor for some problem with bluetooth (SMC and NVRAM reset, deleted system cache folder, boot in safeboot) my iMac’s internal display is stuck at sRGB with oversaturated colors (because the display is a P3 one) and even if I try to apply a different color profile it just doesn’t make a difference. It’s like it can’t load the color profiles (not even the default “iMac” one).

I tried again SMC and NVRAM reset, booting in safeboot (and it happens there as well), and deleted the “colorsync” folder from system’s library folder as long as the “com.apple.color-something folder from the ~/Library/Preferences folder (nothing helped so I restores the folders back).

Any solutions??
