Are you sayng this because with Peak Luminance OFF, in SDR mode the White Subpixel is deactivated and the WOLED panel is effectively operating like an RGB OLED?
My simple math says that when cranked up to peak white levels of ~900 Nits (10% window), about half the lumens are making it through the White subpixel, the other half coming through the combination of Red, Green and blue Subpixels.
So deactivating the white suboixel ought to reduce 10% peak white in HDR mode by half to ~450 Nits.
In SDR, ABL limits peak white to ~350 Nits (10% window) so the same logic would say you'd only get ~175 Nits with the white subpixels deactivated.
Full-field is a little trickier (and also probably less important): the ~150 Nits the C8 delivers full-field is presumably being limited to that level due to power consumption limitations (and heat). When deactivating the white subpixels, lumens drops to ~75 Nits but power consumption also drops by ~25%, so in theory, the RGB subpixels could be driven ~33% harder to deliver ~100 Nits at equivalent power consumption as the 450 Nits being delivered with the white subpixels.
Has anyone measured full-field sustained peak brightness with Peak Luminance OFF?
I'm curious to understand whether Peak Luminance OFF transforms a 2019 WOLED into an RGB OLED able to deliver plasma-like color accuracy at plasma-like brightness levels of 120-150 Nits...
