Relative colorimetric intent preserves colors from the source image intact if they can be displayed on the target device (mean iPad), and shifts the colors that are outside of the target device color space. Thanks to that all iPads have an IPS matrix of a high quality, iPad delivers a rich palette of colors. So the quality drop of the converted images should be small.
In the opposite, application of perceptual intent leads to the proportional compression of the source color space to the target one. This could potentially result in surprisingly dimmed colors.
