Amplification doesn't appear to shift any pixels to different location on any setting. It does however alter the colours of the image.
At around +/- 5 decibels, colours seem to react the most violently. From +/- 5 onwards, shades either seem to wash out (-) or darken(+).
Blues and reds seems to be the least susceptible to drastic change whilst the yellow and green tones alter substantially. Black also appears to lighten to a green hue in the negative values whilst the positives exhibit less pronounced tonal differences, albeit with a darker overall brightness. In each case, the black to white gradient is rendered as a series of shifting, coloured lines.
