Auto Brightness Enabled vs Disabled

[majiklantrn]

One thing I noticed is when the phone has auto brightness enabled, the pixels turn darker taking a medium gray to a darker gray almost a purple. If I disable the auto brightness and have the phone brightness set at 25%+, the grays look correct and pop.

I am just looking for some AMOLED education but with auto brightness enabled, does the display technology power down the pixels to conserve power enough to distort the actual color that should be showing? I believe my Galaxy Nexus did this but I don't remember.

I tried my best to describe this.

I've always turned it off because it's a battery waster, but I'm not seeing it when I toggle it right now.

I attach photos that might help explain the issue. This could be my Mobile Phone OCD issue I suffer from.

Anyone? I might take a trip to Verizon and compare.
