1) I believe there is an error in the computation of the hsb(...) hue value in txt: output.

convert -size 1x1 xc:blue -colorspace hsb txt:
# ImageMagick pixel enumeration: 1,1,65535,hsb
0,0: (43690,65535,65535) #AAAAFFFFFFFF hsb(170,255,255)

Hue=360*43690/65535=240=360*2/3 for blue

The value of 170=255*2/3 is not correct for blue

2) When getting the same color as hsl, the hsl(...) entry is in percent. Perhaps both hsb and hsl should be consistent on use of percent or raw values.

convert -size 1x1 xc:blue -colorspace hsl txt:
# ImageMagick pixel enumeration: 1,1,65535,hsl
0,0: (43690,65535,32768) #AAAAFFFF8000 hsl(66.6667%,100%,50.0008%)

The value 66.6667%=2/3 so is correct for blue
