The Night profile appears to use AT709. I think the DAY profile is similar except it uses high lamp.
I am trying to figure out if I would be able to continue using these profiles with the pany. And if yes, what would be the o/p setting on it?
Currently I let the JVC flip to HDR pciture profile when I play a 4k disc using my sony X800
1... just like how you use your x800 with an hdr output, you could try the 820 in hdr2020 output mode, but with the optimizer on. Try both of chad's hdr custom curves and see what you think. This could let the 820 optimizer function make chad's curves perform well with more titles.
2... the alternative, use the 820 is to switch to using sdr2020 output mode, and you would be skipping chad's curves entirely, and using the projector settings for regular hd material + a 2.4 gamma setting.
When watching a sdr hd, you use the rec 709 color profile. When watching an hdr movie you can use the bt2020 color profile, or you can trade some color depth and gain some image brightness using the hdr color profile.
High and low lamp would work the same, using high when you need that extra image brightness.
Color temp is the remaining area you can pick up some image brightness. Chad probably calibrated your 6500k color temp. Did he do any others? Chad made me a custom 7500 and a custom High Bright color temp settings. These two color temps alts are progressively brighter, but also more blue and blue/green. However, they are effective for viewing with some light on in the room, like superbowl viewing. In fact for football, i run the stock high bright with green gain at (-10) for just a little more brightness and the extra green push does not offend on football content.
Please review the 1st post in this thread and let me know if you have any questions. I cover both, how i used chad's curves and my favorite projector hdr tone mapping., and i cover how i set up for using the 820.
