'Pipe CSC enable' bit is more than just deprecated in ICL+, it was disabled in 077ef1f09c25 'drm/i915/icl: Don't set pipe CSC/Gamma in PLANE_COLOR_CTL' for primary and sprite planes as it was causing those planes to be rendered as always black but it was not disabled in cursor plane, also causing it to be rendered as black. As mentioned in the commit referenced above, this is a workaround too and the CSC and gamma per plane values needs to be setup before enable CSC and gamma again.
