Brightness changing after monitor calibration

Hello, i have an odd issue. I have an imac 5k late 2015. Purchased x1 display pro for calibration.

After i do the calibration for 100cd everything is ok.

Next day i come to computer and i notice that the screen is brighter.

So i decided to do test. I was in complete dark room. Do the calibration for 100cd, after it i did uniformity check with results 100cd. Opened google and on white area measured light wit sekonic with a f4.3 result. Next day i noticed that again brighter screen, so i repeated the test. Started with lightmeter, voala f stop was now on 6,3 already. Did the uniformity check with all areas at 160 luminance.

I didnt do any setting change, didnt switch profiles, didnt adjusted brightnes. Autobrightnes, night shift., ambient measure...everything is turned off. I even disabled the quick Fn keys for birightnes to not change it accidantely

Any idea?
