    At 8-bit ADC it works much better; very little (if any) variation. Since I only need to adjust the brightness between 75-100% maybe 8-bit will be OK.

    Could the 0.1uF cap across Vdd/GND have an effect here? I just swapped out the one on the breadboard for another and now the readings seem stable.
