4K At 30 FPS Isn't.... 4K At 30FPS ??? What?

In my discussion of products I'm getting, I mentioned (in a thread) that I wanted units which did 4k at 30FPS. These are H.265+ cameras, which have a MAX bit rate of 10Mb... and a single (healthy) 3.5" hard drive does 150+ MB/s...

Dahua *81230* all say they do

12MP @ 20FPS
and ...
UHD @ 30FPS

To which, this member said that it doesn't "really" do that. Wait, what? This is a finite, mathematically expressed statement. It either does or doesn't, and math is the only truthful, finite language devoid of ambiguity.

I GET that WDR is subject to spurious claims which contain subjectivism; but a resolution is counted numerically; and the number of frames which can have different pixel content is numeric. These are finite, clear commitments.

They're counter suggestions were H.264 Axis cameras, which I wouldn't be surprised if they were better. I'd bet everyone here knows more than I do across the board of surveillance - and would only have some trouble if I could choose very specific subjects from which to debate knowledge.

But Dahua's statements seem like one's that lend themselves to epistemic claims. How is this errant? I DON'T, get it. What can I trust if not numbers that are expressions of unambiguous, discrete events?

And if not Dahua.... I want H.265+ (plus is showing HUGE improvements of efficiency in my testing so far), 4k (PPF... this is what's good for me), and 30 FPS is my hope. MAYBE 25 is okay... but I'd prefer 60! :)
