Nope, both are about the same - both are filter based - and have similar accuracy.
You need the same number of measurements for calibration regardless of the probe - this defines the accuracy of the LUT - lress samples less accuracy, regardless of the probe.
In our evaluations the K-10 was slower than the Hubble when measuring dark colours.
But both are good probes, and work well with LightSpace
If you want ultimate accuracy go for a PR-655, or Jeti 1211.
But for very good general calibration the i1 Display Pro is fine.
And a deltaE value means nothing for true calibration as it is a 1 dimensional value.
You need to compare the colour space in true 3D space to see the variations.
