That's not how it works.Oh, we are very similar
I have brightness to 39% and Gamma to 2.2
I can't understand users who complain about the NITS specification being too low in general, because if I set the Kuycon to 100 brightness, I would eventually lose my retina completely!
For example, take a look at this night scene. The lamps might be mastered to 1000 nits yet the average of the entire scene might be below 100 nits.
A 1000 nit display would be able to show those lamps as intended, and would also show the differences between lights and objects at say 1000 nits and 500 nits, whereas a 400 nits display should show them all the same and dimmer, with details missing.
