What is this I read about the new HL calibrators that don’t do black well; low light, compared to the previous generation ?
Correct. The new meters use the same L2F sensor as the old meters. But now the peak nits is rated for 3000 or 10,000 rather than 2000. So they reduced the sensitivity with some filter, meaning it’s less sensitive to low light patterns. And indeed in testing this has shown to be the case.
If calibrating things like projectors and OLEDs, You are better off with e Calibrite Plus.

If you only have one or two OLED is the upgrade justified and is there any chart comparing the HL with previous generations with regards to low light differences ?

Upgrade from what? It’s a straight up downgrade from a Calibrite Display Pro for a display that is less than 2000 nits peak white which is all OLEDs.
It stops reading around 0.004 nit vs 0.001 nit on the Calibrite Pro and Plus.

When using that image do not forget to include that pattern is 10bit (RGB input number).
It can be deduced on an indirect way ( 0.0045 nit on an << 100 nit display?) but image alone may be misleadingWhen using that image do not forget to include that pattern is 10bit (RGB input number).

And then below where the old meter read about 0.007, the new meter just fails to read at all, where the old meter would keep going to around 0.002.
I can see how this can cause problems when calibrating near black on a JVC projector or an OLED display, or even a local array dimming LCD.
any thoughts on the new portrait c7 hdr meter? the specs say 0.002nits up to 10,000nits and iirc old meters had 6 second max integration time.
Is it supported by ArgyllCMS? Does someone willing to buy one and send it th Graeme + dev cost?
If any is “no”, out of the question.Feels like a stretch.
This is made by Portrait who makes CalMAN and they seem to be saying that it will only support CalMAN. So not even working with LightSpace or ChromaPure etc.
Maybe Graeme can work some reverse engineering magic, but who knows if or when he would even try.
SirMaster is correct, the meter was designed in house by portrait engineers. disregard the speculations in my above post.
“Hi, it is developed in-house by our own engineers and color scientists, and it works with Calman color calibration software only. You find detailed info here: https://www.portrait.com/c7/”

Looks like Apple way but inverse. We offer you a $300 device but for full functionality pay Studio/Ultimate $1,995.00 /$2,995.00
