Ah, because on my Windows machine it said that the effective bit depth was 10 bits (sometimes, unless the Nvidia driver starts glitching). I interpreted the inability to determine as something being wrong but you’re saying that it’s actually good news?
I test if it can measure a difference. It is not an actual test of VCGT bit depth.
“8bit” means “I can measure truncation”.
“>8bit” (or even cannot determine) means “I can measure that after varying VCGT beyond 8th bit I can measure a change in output”
8bit bad, otherwise ok (although even with >8bit actual dithering is prefered to avoid banding caused by VCGT calibration loaded to GPU)
