In all endeavours where pixel-perfectness was pursued, it ended in tears for everyone involved. UXers because they could not get what they want and if they got what they envisioned, it still was not what they want as they learned about subpixel-perfectness. For programmers as it was chasing a unicorn. For the business because it is an expensive exercise gaining limited value.
Every time I see pixel-perfectness claimed I immediately approach it with a lot of caution.
