I have noticed a very large difference in the whitepoint actually measured (the 0 0 0 0 point in the .ti3 file) and the whitepoint stored in the 'wtpt' tag in a profile generated by Argyll.


Measured whitepoint (from .ti3 file):  97.510 0.78000 -2.9600
Whitepoint from wtpt tag: 89.079722, 0.552168, -2.911983

The difference seems huge to me. Can someone explain how it may have come about?

The profile was made with the following argyll command:

profile -qh -bh -ni -no -l333 -kp 0 0 .8 .4 .5
