I might be wrong but I feel like this is not Amelia's last nose job. I feel that in 5 years she will have it corrected again because the truth is that even though you can see a change, it's still quite discrete and similar to what she used to look like. Her nose is still "long" and the point still droops down when she smiles, which is essentially what she didn't like after her first nose job. Not saying that she should or that it looks bad now, but I think she hasn't achieved what she truly wants and will find herself in a similar situation 5 years down the line. Good for her considering she has the money and can spend 21,000 on nose jobs.
Something that I believe would make Amelia less aware of her nose would be changing her eye make up. She makes her eyes look even bigger, further apart and more "bulbous" than they are by using 100 coats of mascara and highlighting the duck out of her inner corner, which essentially points out the fact that the bridge of her nose is quite wide. Sometimes we become used to something and aren't able to see that something different would suit us way more, which I feel is what happens to her with many things (hairstyle, makeup, clothing...)
