mpv dithers by default, I'm not sure any other players do. You can achieve comparable shots just by turning on dithering, but how each does it is definitely not standardized. I'm pretty sure mpv injects a tiny bit of noise in the process to "boost" the dither for many scenes that are already flattened in the source; MadVR will do something similar if you set it to 6-bit output, which isn't ideal, but beats flat washed-out surfaces on bad 8-bit video. MPDN had a fantastic renderscript to inject a tiny bit of noise via shader, but I haven't been able to get MPDN to run in years.
