Define reference and Compute  ΔE2000
   Start with Source space, generate RGB's Lab values, our Reference data.
   1. Convert from Source space to sRGB with straight Relcol. 
        Compute Lab and compare it with Reference. Refer to first Diagram below for result.
   2. Convert from Source space to sRGB perceptually with sRGB_D50_jc1. 
        Compute Lab and compare it with Reference. Refer to second Diagram for result.


Observation
No color degradation was observed with Perceptual rendering using output profile, sRGB_D50_jc1.
