Question about Monitor Brightness Distribution

[Quincy Fable]

I've been wondering for a long time now if percentage figures for brightness distribution really matter when purchasing a laptop for professional photo editing. I read a review about a laptop I want to purchase (on NotebookCheck) and it says that it has a brightness distribution of 86% and a maximum brightness of ~400 nits, but I like it because it covers the sRGB spectrum and it is color accurate.

 

Are these figures important, or something that I should worry about? Would I notice any issues during normal use and while editing photos? Does anyone have any experience with the effects of brightness uniformity on their monitor? I'm asking this so I can stop freaking out about the topic and I'd appreciate any answers.

 

Thanks!
