I keep reading these comparisons about the NITS on the Note 8 vs the iPhone 10. Older reviews state the Note8 is 1200 NITS of brightness but these recent comparisons say it's only 408 NITS and the iPhone is a record 574 NITS. Are there different kind of NITS that reviewers are comparing?? Why would the Note 8 NITS be inferior if they make all of them?
