I get where some of these come from (48 is the DCI-P3 projector, 80 from 
sRGB, 100 in various places as "SDR max luminance", 160 is Adobe (1998) 
RGB white luminance, 203 is HDR Reference White from BT.2408-5).

500,600,1000 are the minimum peak luminance VESA DisplayHDR performance 
levels (but 400 and 1400 are missing).

Could you explain 235, 300 and 720 please?

Also when we say max, do we mean max full-screen or max restricted area?
