Billion Colors

[Zorast]

Another question:

Can you add support of selecting "billion colors" in Dummy ?
I recognize that the M1 MAX does not show anymore "Billion Colors" on my 32" Apple Pro Display XDR.
With Intel/AMD is was there!
I notice that when using SwitchResX, there was 2 option: "Million Colors" and "Billion Colors"

On M1 System Report does not seem to show pixel formats anymore (at least on Monterey), so the only way to figure out if the Mac is actually providing 10bit color depth is by looking at some grayscale test images and see if there is banding or not. But I might be wrong about this. There is no way to set this in case of a Virtual Display as well (as far as I see) so BetterDummy won't be able to change this.

Can be testet here: http://www.bealecorner.org/red/test-patterns/

I see some little lines with 32" Pro Display XDR when playing the test Video. But I think that will also be the Dirty Screen Effect this Display has. When i open 8bit and 16 bit picture i see no difference, so i think my Display is on 8bit.

It might be. As PhotoShop surely supports 10 bit color output, there are some light grayscale-to darker grayscale banding PS test files to see if the display does properly output 10 bits or not, but probably this video test indicates that as well.
