Does the sample get better if we used splines instead of linear functions to interpolate?

Why do we sample from each direction for bi-linear? And also for an image would that mean sampling from all neighboring pixels instead of just two directions?

Is the type of interpolation/reconstruction filter chosen based on the image content (so that we can decide which one reconstructs more accurately)?
