Thank you, Lyude, for the detailed answer; it makes sense. The bandwidth point is fair: my sink tops out at 225 MHz, so deep colour at higher resolutions was never exercised here. I withdraw both series, this one and the HDMI Deep Color series v2. Please treat them as a proof of concept, in the spirit of the ray tracing work, if any of it is useful.
Where can I find the other developer's work? I would be glad to test it on my bench and report back with a Tested-by: a GA106 driving a Sony KDL-46HX855 (HDMI 1.4, Deep Color 30/36, no VCDB), including 12-bit frame-packed 3D at 222.75 MHz and full against limited range on a sink without a VCDB.
