Hello,

i am using the i1 Display Pro to calibrate and i have noticed that when i compare my old profile to the new one, the new one has a grey/greenish tinge.. does anyone have a guide to properly calibrate an iMac 5k with the i1 Display Pro?

Thank you

That looks like a good and comprehensive guide.

I'd just like to add that if this is one of the new DCI-P3 panels (Apple's variety of wide gamut), it's possible that it uses "GBr LED" backlighting, not "White LED", and the software should be set accordingly. This will affect the measured white point.

Most traditional wide gamut panels use GBr LED.

Generally, the calibration targets should be set to match the paper/final output (not the other way round). The numbers aren't important, D65 or otherwise. Let the numbers fall wherever they want. Just get that monitor white=paper white match.

Temperature is just half the story. That's just the yellow/blue axis. There's also a green/magenta axis to consider, and if this can be adjusted do so.

The 2105 27" iMac with Retina 5K display does use a GB-R LED backlight according to the statements here. If you haven't done so already try selecting 'RGB LED' in the i1 Profiler 'Display Panel' settings and recalibrate the display. This might be helpful:
