Standard/Bright - ~37.9 candelas per squared meter (or 11.06 foot lamberts)
Medium - ~21.8 candelas per squared meter (or 6.36 foot lamberts) - 42.5% dimmer
Dim - ~11.8 candelas per squared meter (or 3.44 foot lamberts) - 68.9% dimmer

So my guesses of ~60% and ~40% lower were pretty close. :)

For comparison, generally ISF/THX calibrators calibrate flatpanel displays to have a peak white measurement of 30-35 foot lamberts for a dark home theater environment. VA LCD panels usually have a black level measurement between 0.012 - 0.014 foot lamberts. IPS LCD panels usually have a black level measurement between 0.04 - 0.05 foot lamberts.

Here's some photos I took, my gaming tv has a high gloss finish with no glass covering. Blue light bar.

Best case scenario - bright room, same coloured background

DIM is dim enough that it doesn't glare any more and if you play in a lit room other things probably reflect more brightly than the light bar.
