My guess is that what you're seeing is probably a side-effect of the scaling changes madshi did, resulting in smoother chroma even on nearest neighbour.

There is definitely some kind of filtering going on, as I have chroma and luma both set to nearest neighbour. The decoder may not be the issue then, if LAV CUVID can only output 4:2:0.
It's my understanding that the new feature scales chroma to the luma resolution using your selected chroma algorithm, and then both are scaled to your display resolution using the selected luma algorithm.
MadVR 0.12 (went back to it to get a direct comparison when testing, but anything below 0.62 is the same)
MadVR 0.62:
This is with MadVR set to Nearest Neighbour on both.
