5k iMac 2017 calibration quality

[snap01]

Just profiled and calibrated the screen on my 5k iMac 2017. Wondering what type of deltaE errors people are getting with their screens.

For average results

Total: 0.64
lowest 90%: 0.6
highest 10%: 1.01

are those good results?

They're good, but dE76 is not really a modern way of measuring, better to use dE2000 (which usually gives you worse scores, but it's a much more correct way of measuring)
A Delta E of 1-2 is perceivable through close inspection, you really want <1 if color rendition is important to you (1.01 is going to be really hard to spot).

To be honest, I wasn't really sure what was good and was hoping other photographers would chime in. As Tozz noted, I did read that a deltaE score of 1 was threshold of human perception, but I don't really know how the errors for the P3 screen on the iMac compared to other screens geared towards photographers (i.e. wide gamut).

Also my software is old and only measures 24 patches...
