Hello, @KelSolaar Thank you very much. I suspect the official Spyder software might be referencing my computer's ICC profile to calculate RGB values. Attached is my current display color profile: Given that I've already obtained the XYZ measurements for both the white reference card ( Best |

I have been researching color measurement using the SpyderX Elite.
I have some very confusing questions about it. Can someone help me? Thanks!
I found that when using the SpyderX to obtain Delta E values, my own calculations do not match the results from Spyder's official software. Specifically, when I read data from the SpyderX (using the open-source code for hacking SpyderX on GitHub), my Delta E values differ from those reported by the official software.
Example
Lab = [83.61, 3.36, 87.02]
(243, 205, 7)
(I took a screenshot)0.27
However, in my own calculations:
[0.623570, 0.298768]
[0.310583, 0.593947]
[0.120839, 0.069452]
(255, 255, 255)
image using the SpyderX:[390.636366, 414.663251, 498.881663]
(243, 205, 7)
using the SpyderX:[247.880162, 252.762201, 49.025823]
2.763
I've attached my code below.
Can anyone help me understand why my results differ from the official software?
Thank you very much!
