Have checked my S550. It passes vertical detail clearly at the highest chroma multiburst but horizontal resolution looks a bit suspect... the blue lines don't look full amplitude compared to the vertical multiburst at the same frequency...

Given that blue is the colour we're least sensitive to I do wonder if this is a visually perceptible issue though in images (not test patterns)? Having said that, I would, as a principle, like my players to deliver everything on the source...
