You probably have the texture color space wrong. ACES can be annoying that way.
- Base color/ color texures: Utility - sRGB Texture or role_matte_paint
- HDRIs : Utility - Linear sRGB
- Non color data: Utility - Raw or role_data
I created an addon that auto assigns the color space based a tag in the texture name e.i. Character_BaseColor or Character_Normal
