wrong colors if you playback UHD blu ray with HDR on a non HDR compliant display?

It's the average light level for the whole frame, yes. But that doesn't mean that the image is restricted to 400 nits, it means that you can have a 1000-nit specular highlight (like sunlight glinting off a windscreen or something) as long as it averages out against the brightness of the remaining imagery in the frame.

MaxCLL tells the display what the maximum light level of the content is (up to 1000 nits) and MaxFALL tells the display what the average light level of the content is (up to 400 nits). That said, Stacey Spears said he'd found out that the Warners discs appear to be carrying the data for a maximum light level of 4000 nits (as per the original Dolby Vision grade) so **** knows what's going on there.

Hell, perhaps that's why some people (was it Adam?) were experiencing weird goings on regarding the Warners discs looking washed out compared to others that they'd viewed?
