If M31 were 4 times closer, it would be a spectacular view in a
moderate aperture telescope at about 75x and an eyepiece with about a
1/2 degree field of view.

FYI: the apparent length of M31 in our sky is some 3 degrees. If it
was 4 times closer it would appear 12 degrees across. A field of view
of just 1/2 degree would then only show a small part of it.

So? The details in M31 would be more apparent in any given telescope, binocular or camera.
