Hi ondrejh71856982, The H.264 is an excellent video codec but it is compression and especially affects the colorimetry, not the luminance, because the human vision is more sensitive to the changes of luminance than to the color ones, for this reason the changes in the color compression is less noticeable. However, the trained eye can not be deceived, yes it is a little opaque if we compare with the original video. If what you need is to have an excellent quality of video you should use for example an Apple ProRes codec if it is for broadcast, but if you need it for Web if it is with the H.264 codec. Surely the Wondershare internally applies a bit of saturation so you do not notice the change when compressing your video, and if that's how you need it, perfect!
