38 & 42 screen brightness differences

Has anybody compared two watches to see if they have identical screen brightness? I thought I was going crazy at first but somebody else commented and it's clear that the 38 is brighter, equivalent to the 42 one brightness setting higher.

I'd usually out this down to different back lights but OLED has each pixel individually illuminated correct? Could it be that the smaller pixels on the 38 make it seem brighter?

Pictures aren't great (iPhone 5...) but should show what I mean. The 'blown out' colours show in reality as a brighter image.

I'm not sure if this reveals anything, but I believe the pixels on the 42mm are actually smaller than the pixels on the 32.

This could just be a natural variance in OLED technology?

That's definitely possible - I've not used an OLED screen before but really enjoying the absolute black it creates.
