Is RGB->YUY2->YV12 more accurate than RGB->YV12?

edit: Actually I need to ammend this while I verify something. But if anyone can comment on the question in the title that would be swell.

Is RGB->YUY2->YV12 more accurate than RGB->YV12?

In v2.58, RGB->YV12 is done internally via YUY2 anyway, so both give the same result.

In v2.60, RGB->YV12 uses YV24 as intermediate.
Chroma subsampling is done using bicubic (by default) with proper antialiasing, so should be better than the bilinear without antialiasing done in RGB->YUY2->YV12.

Interesting. Thanks.
