I haven't seen or heard the album in question, but here are some possible explanations:
- The LP artwork might not scale well down to a CD size (too much small detail?)
- Using identical artwork might convey the impression that it's an identical reissue of the LP i.e. the same tracks
- For those who aren't familiar with the LP, surely it's best to have a track sequence that works well in its own right. Sticking extra tracks on the end isn't likely to be the best combination. Believe me, I've done this. Taking one track out of a proposed album resulted in a reorganisation of at least 50% of the other tracks to make a good listening sequence. In particular there's often an obvious choice for the beginning and end and it's desirable to stay with that.
