Comment (by Balling):

 Again. Wrong. Any modern display is HDR, just because it is brighter than
 100 nit. SDR should be 100 nit max! When you calibrate OLED TV you need to
 set maximum brightness for SDR, and it is 100 nit is dark room and 200 nit
 in light room. That is the point! With hdr you cannot manipulate the
 brightness. Okay? Just cannot!!! HDR manipulation should be blocked (it is
 not on android and in many cases but it should be, okay?).
