I'm not sure; it seems like similar numbers of cases moved in each direction, and I'm kinda inclined to chalk it up to noise. It does look like a lot of them are cases where we round-trip yuv420 -> rgb -> yuv420, and it's possible that the current code path just happens to give better PSNR on that some of the time?
