I have based by measures on a 3DLUT I have verified with my Jeti as reported in my previous post
See, here, for your convenience, the related verification:
So basically something very close to reference whose gray scale, Primaries and Secondaries, saturation and GCD Colour Checker I have re-measured with HCFR with the following meters:
- My Klein, profiled and validated Klein Case)
- My I1d3 Using as display type “Non-Refresh Display”
- My I1d3 Using as display type “WRGB OLED”
You can see here the outcomes of the comparison of the RGB balance of the WRGB Oled case vs. the Klein reading:
and of the Non-Refresh Case still vs. the Klein reading.
Quite clear the improvement of the WRGB Oled in comparison to the “non refresh” case. From a dE perspective, the WRGB Oled appears even better than the Klein case. That's only appeareance: I have gone through the Jeti measurements and I can confirm the Klein one are well aligned (i.e. minimal delta chromaticity, in the order of .001). From a dE perspective it is clear that using WRGB Oled you have an dE error up to around 1.1 (1.4 for the non refresh case). Checking in the attached files you can see a chromaticity error (dxy) of .002 (0.0035 for the non refresh case).
Have also a look to the primaries (and secondaries):
(Klein readings at the top, WRGB Oled at the bottom), you can see the, the Klein very close to NIST requirements (only a little deviation of Red delta L), in line anyhow with what Klein requires for matrix generation. The WRB Oled readings are anyhow acceptable.
For completeness I have also added the Colour checker view:
True that the HCFR GCD colour checker is quite limited and not comparable to a 1000 patches check, but the dE/ref stays, excluding grays, well below 1.
That does not mean that by using a non profiled I1D3 with Zoyd WRGB Oled EDR you don’t need to profile your colorimeter. All my data depend on my I1D3 accuracy, and should be repeated depending the I1D3 you are using. Let’s say I am a lucky guy, but for sure, by using WRGB Oled EDR variances, you increase in dE and chromaticity accuracy.
Attached HCFR files. Hopefully the naming should be clear enough.
