After having my Chroma 5 recalibrated by SpectraCal, I tried calibrating my Kuro LX-6090. I used CalMan 3.7, as 4.0 produced strange results in the 50-60 IRE range, with wildly fluctuating measurements.

I attach my results. Are they of acceptable quality? I opted for the 2.3 gamma target for Day mode by looking at D-Nice results. I honestly don't know whether that's the right choice or not.

The measurements I attach have been done after a session of about... a couple of hours I'd say. This should be plenty enough for the sensor to be at the right temperature, am I correct?

Is this the wrong forum to ask this kind of questions?

I am no pro but you did a good job on gamma and greyscale tracking.
Only wonder why blue gets a dip in 100% in RGB balance (one time measure error?? because your ftl is not that high).

The gamma can be calculated with Y in

100%

10 (0.0060 x 30,7555)
20 (0.0281 x 30,7555)
30 (0.0619 x 30,7555)
40 (0.1308 x 30,7555)
50 (0.2146 x 30,7555)
60 (0.3217 x 30,7555)
70 (0.4530 x 30,7555)
80 (0.6093 x 30,7555)
90 (0.7914 x 30,7555)
100 your Y measure =30,7555 (in nightmode)

If you do the math you see that your are very very close for gamma tracking.
I assume this is looking great on your tv.

Your calibration results are right on the money. Great job.
