I need help with my calibration results

[pppp1]

I just calibrated my 8G Kuro using the Calman software, the Chroma 5 colorimeter and the AVSHD709 disc. dEs for grayscale are all at or below 1 gamma average is 2,17 and i measured luminance at 100IRE at 30ftl. dE94 for primaries and secondaries is below 3 for all except for blue which is just above 4. Luminance graph shows all colours at exactly the target level or a little over.

But the thing that worries me is this: While Delta Luminance and Delta Hue are all below 3 for all colours, delta Color for Blue and Magenta is 15 and 14 respectively. How can I reduce this error? And what does it mean? Does it affect the images I see greatly? And why isn't dE94 greater for those colours if it comprises delta c, l and h?

You need to adjust the CMS to address the colour dE assuming it's within range whilst also balancing luminance and hue dE.

IIRC the dE94 formula factors in colour, luminance and hue when calculating the overall dE94 value. Perceptually the combined components can offset a more significant individual component error.
