Did some investigating on that refresh rate number, it looks like the LED panels use something called Scrambled Pulse Width Modulation (S-PWM). From the little I can understand, it just seems to be a method of splitting and offsetting the PWM signal.
It’s unclear to me if that means that a single pixel could be updated 3,840 times in a second or if the entire display collectively updates that much.
Playing with some math, if you had 4 sub-pixel LEDs updating at 120hz and separated into 8 sections across the entire panel that was each offset in time by some fraction, you could say there were 3,840 updates to the panel across a second. That would be quite the bastardization of the term “refresh rate”, but I could see that being the case.

That’s not really what people have in mind when referring to “refresh rate”.😆
