When does 1000-nit grading NOT translate to consumer TVs?

Hey everyone,

I'm Lucas, a Gaffer, and I've been wrestling with something on a recent project. We shot on an AMIRA, mostly natural light complemented by a couple of SkyPanel S60-Cs and an LS 600d Pro. The DI facility, understandably, graded on a 1000-nit reference monitor, which looks stunning there.

However, I'm finding that when I view the final output on various consumer TVs (my own OLED, a friend's QLED) the image often feels... different. Not necessarily 'bad,' but definitely not always what I saw in the grading suite. It seems like the varying peak nit levels and the proprietary tone mapping on these home sets are creating discrepancies.

My question is this: While the 1000-nit reference is the gold standard, when do you find this 'textbook' approach starts to break down or fail to translate effectively to the wildly diverse world of consumer television displays? What are the common pitfalls you encounter after the grading suite?
