Correct, a7r definitely has more detail than my Canon body's.
There are two things you can get detail of, though. When an image is under-sampled, such as when you have a very sharp lens, and not enough pixel density for it, your image detail gets distorted into pixel detail. Ideally, you would not want to see any evidence that an image is composed of pixels.
Lack of an AA filter works optimally when the lens is only moderately sharp; in that case it avoids any unnecessary softening beyond what the lens does. When the lens is very soft, it doesn't matter if there is an AA filter or not, because the AA's contribution to softness is insignificant compared to that from the lens. When the lens is very sharp, you start seeing false detail, in pattern which emphasizes the geometrical grid of pixels, more obvious to some people than others.
