HDR: Don't assume that swapping between BT709 and BT601 needs tone-map.

Browse Source 
VideoFrameProcessor treats BT601 and BT709 as roughly equivalent now, so we
shouldn't be making checks that assume BT709 <-> requires tone-mapping.

Also, the color transfer is a better determinant for tone-mapping than color range, so use just the transfer to determine if tone-mapping is required.
