they can calibrate oleds, ive had mine calibrated. TOTALLY worth it. 100% recommend. what you want to do when youre setting up the appointment is ask them the equipment theyre using and research that to make sure it's proper for oled and hdr (I don't think DV HDR calibration tech is public yet). The blue shirt isn't going to know, make him or his home theater sup to get on the phone with the calibration agent (there's usually only 1 or 2 in an area) and get them to find out. they'll also calibrate your audio as well while youre out there, just mention you want that when youre setting up the appointment so the agent knows to schedule additional time.
