I also use these modes on my B8, but the gamut option is (!) available in ISF Dark/Bright SDR modes, so I set it to Wide.

I just tested the MMFR sample (keyframe at 00:19 sec, frame peak 6344 without clipping), lum max to see the blue patches. I tried various DPLs 800/2000/4000 and set the clipping according to them: e.g. at 4000 DPL, 40 DC results in 3954 nits. If I use higher DC e.g. 100 no difference in the patches, if I go lower e.g. 39 there is difference (slight) straight away. So this one isn't a bug either Does this mean that there's a lower limit at DPL for this? If so, then why on earth madvr allows the measured nits value to go lower than DPL?! What's the point? I mean, with DC we clearly have the lower limit which is DPL!!! (Unlike with the sky algo where we don't have a specific lower limit, at least not that straightforward.) What am I missing here? This one kept me thinking: are you sure that the sky algo is useful for us? (try it with The Meg (TM) sample) Let's take these two profiles (DPL/DTN/SS): - p1: 800/60/0 - p2: 800/85/100 The purpose of sky detection is the lower the FALL of high FALL scenes so DTN doesn't result in such high ADPLs, allowing to use higher ADPL value (85 vs 60), right? But this one actually has a side effect: - high FALL scenes: -- with p1: they still have high FALL, so we don't need to use high DPL for these -- with p2: they have way lower FALL, so to compensate we need high DPL - lower FALL scenes (not really low ones) -- with p1: we don't have such high ADPLs due to low DTN -- with p2: we will have higher ADPLs (than peobably is necessary) due to the higher DPL!!! What do you think? Quote:
