Support for TV-led Dolby Vision on all devices

I suppose 99.5% of pixels could be below 100 nits and it would show as 100%? Not sure anyway how those 5/10% values can be used to help with conversion to DV.

They may be useful, by using the 5% value (probably not in the “right” way) I was able to reduce the maximum error between the hdr10+ conversion and the original DV average PQ quite a lot. The average error did increase a fair amount though so I didn’t end up including it.

Wait, what? You are converting from DV to HDR10+ now? Or did I misunderstand that.

Misunderstood, I was comparing the the results from a hdr10+ to DV conversion to “original” DV data from a native DV copy of the same title.
