If you're happy with it, I would strongly recommend not checking, your OCD levels will reach new heights if you see something you don't like. 😳😂
Only reason I checked, I noticed straight away without comparing it to my previous phone, I was using my 13 Pro Max at a higher level brightness in the same lighting conditions I would normally use my 12 pro max In, I knew straight away that my display wasn't as bright as my 12 pro max. 😔
Enjoy your phone, don't bother checking, it's 99% percent to me, apart from my screen issue.
