I would assume a retail ready model would have the capacity for that blinding level of nits, but undervolt to a more reasonable brilliant 2,000 and then add voltage over time to compensate for the dimming over time.

I will say that having a >10,000 nit display could be really cool at 8k, you could produce some really awesome images and stare at the Sun without having to go outside and with less cone damage.

Apparently the Sun at noon is 1.6 billion nits, that would be hilarious in a TV.
