That isn't an inherent property of DXVA scaling or anything, its just an artifact if you try to access the 4:2:0 "untouched", because there is no 4:2:0 texture format in D3D9, but when you use DXVA to upscale chroma (or the entire image) anyway, then this doesn't really apply. Its not like the chroma is blurred first and then upscaled, thats not how it works. The method madVR uses to try to extract 4:2:0 subsampled chroma just causes blurring.
