Not Ranked

I dug out my copy of the ADR's and ADR 12 lists items like wiper arms, internal w/screen mouldings, steering wheel, internal mirror, that are in the field of view - which is within a cone of vision with an included angle at apex of 40 degrees and its axis horizontal and
parrallel to vehicle, where the apex starts between the drivers eyes ( there is also a standard on where the drivers eyes are located for measuring purposes).
In effect these items must not cause glare or reflection, but it does not mention instruments, however these items are exempt if mounted below the lowest point of light entry, or are "so located that external light cannot be reflected to drivers eye position".
That last quote pretty much gives them a good argument to disallow chrome bezels.
The antiglare does not need to be black, just have a "specular gloss level" of less than that specified.
But again its up to whether you can convince the engineer and or authorities
