Dull lockscreen wallpaper when using Fingerprint

So I noticed that when I set a photo to use as my lockscreen wallpaper that it looks super dull and washed out. I use the fingerprint lock, so I went into settings and set it to swipe. Well the picture looks perfectly vivid and bright on the lockscreen now. But when I switch back to fingerprint it gets dull.

Can anyone else replicate this bug? If so, what is the cause of this?!
