I think the bond that you have with your pokemon makes no difference to weather it's distorted or not. I recently just thought this up:
It is not weather the bond between one and one's Pokemon is strong, but rather the Pokemon's memory strength. If the image is remembered fully and fluently by the Pokemon, it will pass it on to you perfectly with no distortion, however, if it is not as well remembered as it can be, parts that aren't remembered will be distorted, even distorted enough to be transparent.
This, to me, makes more sense, hm?
