Is there a typical conversion from normal 8 bit images to half that
will properly linearize the image so it looks "right" once displayed
using the half display conversion? I'm finding my images look too
dark once I to through my current process.
Are you currently using an sRGB transfer function to go from 8-bit to half?

(a = 0.055 and ignoring the XYZ matrix)
My results look like what they would if I wasn't, which I'm not. Lemme give that a try!
