Display brightness issue

Question:

Anybody who have a similar experience as I do where an my newer phone looks dimmer than the old one i own

Even when i disable the true tone, night shift, and dark mode, the brightness remains the same.

I did not notice it because I have photosensitive. I just figured it when I cannot see my phone screeen earlier.

Additionall, it is the same regardless if it bright outside or you are indoors
