Besides the potential reasons you listed, which may or may not affect the IQ much, keep in mind that dark regions generally have a much lower signal-to-noise ratio than bright regions due to basic principles of photon counting statistics (i.e., basic physics). Despite the fact that the absolute noise level in darker regions might very well be lower than that in bright regions, it is generally much more visible, because the signal is also much lower.
