Late 2013 MacBook Pro Keyboard Light Bleed Uniformity

Hi. I have a 15 Inch Late 2013 MacBook Pro. I had a swollen battery in it and had Apple replace the top case along with the battery. When I got my computer back from repair I noticed that the light bleed from the keys on the replacement keyboard is not uniform for all the keys. Some keys have very little or no light bleed whereas some keys have significant amount (when looking at it from the front of the computer). The light bleed seems more uniform when looking at the keys from the back of the computer with the monitor fully extended. The light bleed on the original keyboard was more uniform throughout. Is this normal for the replacement keyboards? Would this be considered a defect? Should I schedule a visit with an Apple genius regarding this issue?
