Where I would always expect to be able to see some FPN in difficult conditions on any Ursa Mini 4.6K.
Dara O'Neill wrote:- Applying a grade like you suggested does darken the areas, making the FPN harder to see, unless you have a monitor / screen at a higher brightness setting which then makes the FPN even worse and more prominent because the FPN itself is a pattern of dark on light:
I don't see it under those conditions, but if you are / do, then we have a different threshold for it.
The grade you apply was also heavy handed. With a skilled colourist, I think you'd be able to find something less crushed in the blacks, yet that has the blacks being black.

I suspect that you have a different lens and a different exposure. What lens did you use and at what exposure ?
What's in the image seems different to me. What amount of light is reflected will be different. It's hard to "replicate" this without everything being the same.
The linked image also appears to be "somewhat" graded to me, the blacks are sitting lower than straight ungraded BMD LOG.

BMD would be the ones I imagine, but if you're inside your re-seller's return period perhaps take it up with them first and see how they feel.
To be honest, I'm not sure you've made a very compelling case YET for there being an issue, I think so far in the circumstances that you're testing for, almost all BMD cameras would behave in a similar way. But I can't really tell over the internet
