Good. Adequate. Normal. Right.
Show us:

xicclu -v -fb -ir -pl -g a1.icc
xicclu -v -fb -ip -pl -g a1.icc

If the plots above are smooth the profile is good (takin in account low dE76). 
If the perceptual curves are not quite smooth there may be increasing of -r 
colprof parameter may required. But not likely for your device. It seems yours 
will be O.K.


Take a look at:

iccgamut -v -w -s a1.icc
(VRML viewer is needed).

Check dE2000:
profcheck -k -x -w -e a1.ti3 a1.icc
