DisplaysShouldNotBeTVs
I ran into some color management issues that I need to figure out.
The video recorded by the device uses Limited Range 16-235, which makes white look gray. Switching between Limited Range and Full Range in BetterDisplay for the recorder doesn't fix the issue.
The recorder can also take screenshots (a separate feature from video recording). These screenshots are in TGA format, and in those, the white background in the browser looks white with a value of 255. But there are differences in shades between the screenshots taken directly on the M1 Mac and on the recorder because the profile generated by macOS is not accurate (?). I also tried standard profiles, and it's the same story everywhere; the shades differ.
TGA should be lossless (https://en.wikipedia.org/wiki/Truevision_TGA), but the presence of something similar to aberrations around some colored objects seems strange to me. I need to figure this out as well.
Below are links to screenshots taken directly on my M1 Mac (Screenshot_X.png) and screenshots taken through the HDMI recorder (Recorder_X.tga): https://file.io/7N0aPzOsfdPg
If you need frames directly from the video, let me know, and I'll send those too, but they are in Limited Range 16-235.
