ColourSpace includes a selection of unique pre-set Characterisation Quick Profile patch sets that include Secondary Colours. When these patch sets are used, a totally different Multi-Primary colour engine is used during LUT Generation.
These + Patch Sets are especially suitable for WOLED displays, such as for LG TVs, but generate superior results with any displays compared to alternative calibration systems.
When a LUT is generated using these profiles, a unique Multi-Primary Colour Engine is used, enabling calibration accuracy far in excess of alternative options for such small patch set profiles. Often, generating results that are close to, or even equal to, large volumetric patch set profiles.
User generated .csv patch sets can also be used to enable the Multi-Primary colour engine during LUT generation.
