DisplaysShouldNotBeTVs and would love to provide any info I know that would help in creating an Intel version
@NewDwarf has a technique here for disabling temporal dithering on Intel Macs and also AMD (it's different technique than the one linked by op). I don't believe it was tested with a lossless capture card but some have reported success on Intel Macs.
DisplaysShouldNotBeTVs There's two layers of dithering on XDR Macs
one at GPU level (which Stillcolor does disable) and one at display panel level (which it can't disable)
This is interesting and unfortunate. It's hard to imagine two separate temporal dithering algorithms look good on a screen even to "normal" people?
