Yeah, 0.02 dE00 errors are seriously not worth the time and effort to chase - especially as the cost of time.
The one thing we hear from professional calibrators all the time is 'time is money'.:)

I suspect those differences, which really are just 'down in the noise', and not really worth spending time on, are just rounding differences with the maths used for the final LUT processing.

If you mean rendering intent, that was set to 'Absolute colorimetric', with Tone Curve Rec.1886.

I used the suggested setting you gave me, so all should be ok :)

Ok - the same graph re-scaled - as a quick and dirty stretch - but it shows the comparison better now.

It is on the Distribution, as that graph auto-scaled, but not on the RGB Balance, Delta-E, Gamma, etc., and you can see the difference there.
I'll see if I can 'un-scale' the Distribution graph now...

In the real world change between different brightness levels are nearly always relatively slow.

The chip is not the same as in the PR probes, which is why the CR-250RH is so good compared to more expensive probes.

Delivery is on a relatively long lead time at the moment - about 2 weeks, but...

I actually don't know that any manufacturer that has listed their final values.
