I don't know how much difference there is between an out of the box i1 vs a profiled i1 against a better meter, and without checking it for accuracy using a more laser compatible meter I won't know for sure, but unless you really want the knowledge of 100% accuracy for piece of mind, I would say that the i1 Pro is good enough for simple home calibration of the laser Epson. Greyscale ramps look fine too, with no obvious colour tints. Now, I don't know if that was down to the new/different screen material or the i1 not being accurate enough for the laser (or a combination of both), but after I recalibrated and made a memory, I can't see the difference between the two when doing A/B comparisons. It had been calibrated previously on my old screen (using a better meter - may have been a Jeti), and when I checked it on the new screen it was out a little - the blue was a bit high IIRC. I picked up a profiled i1Pro recently and checked my LS1000s greyscale calibration with it. I'd probably be much richer and have watched more movies and less test patterns if I'd just paid someone, but it can also be fun learning about something. It is the kind of thing that can be done quickly by someone with the gear (maybe in passing on the way to another job).Ĭalibration (well, any sort of metrology interest) can be a bit of a rabbit hole as you very quickly discover the limits of the consumer level equipment. If you wanted to really get into colour correction yourself of a laser PJ, relying on the readings from your i1 display pro, you'd probably want to try and have a calibrator who has a sufficiently accurate spectro profile your meter to your display.

Jeti have a white paper that describes the issues here (though with the example of a full RGB laser):

It is reckoned that you need at least 5nm to do a good job on laser projectors, which puts you into having access to at least something like a Jeti 1201 or better (I got a good deal on a used one, but factor something like £5k for new.!) 10nm is not generally regarded as narrow enough to characterise the blue laser light.

Cheap spectros like the i1pro1/2/3 (not to be confused with the i1 display pro colorimeter) usually have something like 10nm bandwidth (though there is a software tweak to 3.3nm with lots of caveats). The blue laser light wavelength is very spikey (in fact, I think 2 sharp spikes for Epson laser).

To create a correction yourself you need a spectrophotometer or spectroradiometer of appropriate resolution. i1 display pro doesn't come (I believe) with a correction for blue laser + phosphor wheel, so there isn't an obvious out of box setting that will be colour accurate, though you should still be able to use it to some extent to see if gamma is reasonable, if the RGB balance is flat (if not colour accurate), and how saturation tracks approximately. With colorimeters like the i1 display pro you need to have a correction ideally for the displays you are measuring.
