DV just can't show "washed out" colors. It can do either good or totally wrong colors.
The _only_ option for now for the proper DV colors with SVP is SVP's provided mpv build.
And I personally can't see any color difference between RIFE and non-RIFE interpolation here.
If colors are washed out then it's HDR10, not DV.
Not sure what happens for the "hybrid" releases when there're both HDR10 and DV in the same video file
