That looks pretty good.
Have you tried measuring the colour gamut at 75% in case the colour gamut isn't linear? If you find the 75% results have larger dEs then you have the choice to calibrate at 75% instead of 100%. As 75% is more representative of actual video content, then some prefer to calibrate at 75% if there is a variation in the response.
