It seems quite some got light bleed or yellowish issue. Yellowish I may got as slight different in grey at keyboard but not obvious, probably 0.5% differences.
As for light bleed, my unit was fine after tested with blacklight bleed, lucky it was as I stay at Malaysia where replacement was out of possible.
My unit was R32CC, 100% seal not broken.
