From: Niklas Haas <g...@haasn.dev>
Before cedf589, this function would return early return on RGB and float
formats, as well as when range was equal. While this commit
intentionally removed the early return for same-range YUV conversions,
it missed that RGB and float formats that have an unscaled converter
should always early return, no matter what the source range was set to.
Fixes: cedf589c09c567b72bf4c1a58db53d94622567e1
