DXVA2 copy-back, D3D11 copy-back, D3D11 native and software decoding have perfect picture quality. But D3D11 native doesn't support deinterlacing nor black bar detection. If you don't need those you can use D3D11 native.

UHD BD Menus in jRiver also need copyback (they don't work with native).
So it's not just for black bar detection that we need copyback.
Also D3D11 native is the fastest mode to measure files with madMeasureHDR for many.
So there might be some frequent switching involved between native and copyback, at least if you use measurements files...
