Is this a known fact/problem? How to determine the right sensor orientation?
It depends on the instrument. It was something that's quite noticeable with the Spectrolino, but much less so with the i1pro. I'd be surprised if the ColorMunki was worse than the i1pro. To check the effect, throw up a test patch using dispwin -m, and then use spotread to check the measurement at different angles. You can use 'r' to create a reference and then see the delta E. If there is nothing better to go on, I'd stick to the manufacturers recommended orientation. Graeme Gill.
