The source format doesn't matter. Any source will do, 4:2:0, 4:2:2, 4:4:4 or even RGB. We're not talking about 4:2:0 -> 4:4:4 chroma upsampling here, but about "doubling" the chroma channels when the luma channel is doubled with NNEDI3 at the same time. With v0.87.21 you can double chroma in the "image doubling" settings page. Or you can switch "image upscaling" to Jinc3 AR, then that will be used for doubling chroma, as well, if NNEDI3 chroma doubling is disabled.

Jinc3 AR does cost a lot more performance than Catmull-Rom AR. The difference should be noticeable even on a fast GPU. It might not be a night-and-day difference, but even saving 2-3ms can help if you want to use other algorithms, as well.
