I have not yet seen one that is "fine", and would like to see one.
Every single machine I have tested, included the one from office, all of them have problem shown right away with either on the common 4xTree test, or simply gmail inbox with gray color differentiate from left to right (looks like gradient but there are none)
At this point, I honestly dont believe there is a single panel that doesn't suffer from uneven tint for TouchBar Macbook.
It's all about tolerance level. It might be "fine" to you, but not to the others, especially for those who do design development.
