This issue isn't automatic brightness, it's OLED, which can selectively light portions of the screen, vs LCD, which has the whole screen at the same brightness all the time and blocks light.

A LCD with a global light source won't benefit from dark mod. A LCD with more localized lighting will benefit some. An OLED will benefit the most.
