Hi - as you say auto-iris is a lot like ABL, and if you treat it the same you should get acceptable results - possibly even very good results.
We do have a lot of users with similar technology displays, and all have reported 'good' results using this approach.
What I would suggest is using the free DPS version of LightSpace, with your existing i1 Pro, and doing a full profile.
Then send us the profile to look at and we can let you know what we think final calibration is likely to be like.
That should give you a realistic answer as to what to expect.
