When rendering gradient of luma values you can clearly see that the monitor output from Apple Silicon GPU has lifted/curved blacks (values 0-31 out of 1024 in 10-bit output).
Any idea what is going on and how to remediate? It looks like some kind of compensation/calibration for the screen panel response, but it is baked into output regardless of what kind of monitor (or non-monitor) is connected.
The same rendering on Intel architecture produces correct linear gradation. We have tried M1, M2, M3 and they all seem to be affected.
