I don't own an iPad. However, on my display (giant 30" panel), I can easily notice the difference between resolutions that are 4X different in pixels. You can see it in the lines and many different aspects.

Ultimately, it comes down to how good your eyes are (i.e. angular resolution), distance from display and pixel area.

But 4X more pixels should be quite noticeable.
