IM 6.4.1-9 Q16 non-hdri Mac OSX.

There still seems to be an inversion of the alpha value in -verbose info for graya images.

convert -size 100x100 xc:"rgba(100%,100%,100%,0)" white_rgba0.png

convert white_rgba0.png -verbose info:
Colorspace: Gray
Depth: 16/1-bit
Channel depth:
gray: 1-bit
alpha: 1-bit
Channel statistics:
gray:
min: 1 (1)
max: 1 (1)
mean: 1 (1)
standard deviation: -0 (-0)
alpha:
min: 1 (1)
max: 1 (1)
mean: 1 (1)
standard deviation: -0 (-0)
Alpha: rgba(255,255,255,1) #FFFFFFFFFFFF0000

The problem you posted is fixed in ImageMagick 6.4.1-10. Thanks.
