Looking for feedback on my first backlight/bivert installation!

[Herodotu5]

Hello! I recently completed my first backlight/bivert mod on an original gameboy DMG. To me, it looks a little bit faded, especially compared to some of the examples and pictures online where the pixels almost seem perfectly black. Since this is my first time doing this, I thought I would post and see if this looks normal, or if there are any ideas of anything I did wrong. Thanks for any feedback! Here are 2 pictures (sorry, had trouble getting them oriented upright):

Looks to me like you just need to tweak the contrast a little
