No, the result. Distinct red cast.
There's a lot of options in this BasICColor software, including a "hybrid" hard- and software calibration. I have to look into it in more detail. Problem is I'm bringing lots of work home the next few days and it'll just have to wait until later, as long as I have a workable i1 calibration.
But I did notice one peculiarity with the display itself. There is a distinct off-axis purple glow in the blacks, but only when viewed from the left side at about 45 degrees angle and more. Viewed from the right, at exactly the same angle, it's pure black as it should be. Weirdest thing.
I think I can live with it, it's no big deal in practice. But weird. In any case I've returned enough displays in my time and I'm just not doing it this time.
