If High Quality mode is calculated with 16bit colour and alpha channels, is HDR output possible, or are the Composition and output devices (screens, Spout, virtual devices, NDI, whatever) always downsampled back to 8bits per channel (eg by a value >> 8 kind of operation)?

If it is possible to get more than 8bit output, what hardware examples are there of this actually known to work, and what are some of the details (eg bit depth, any kind of HDR scheme used such as PQ or HLG)?

All textures are downsampled to 8 bit when they leave the application. Theoretically, Syphon and Spout could remain 16 bit, but we've really heard of a convincing use case for this.

Personally, I do not know of any broadcast video display devices that work at 16 bit, but I'm mostly on the software side of things.
