I have 2 DMM6500, one is 2 years old, the other is brand new

The brand new one has a washed out screen when compared to the older one. Both are set to the same brightness level and the screen protector makes no difference. Both are running the same latest firmware.

I appreciate that they possibly have different screens, but there seems to be a lack of quality control if there is this much difference

See the attached picture
