rtc-screen: Fix color artifact via color_sensitivity

Reduce the threshold (increase the shift) for setting
the color_sensitivity to 0 at superblock level on
scene/slide changes. On scene/slide changes better to
be much more conservative in setting this flag to 0/off.

This removes/reduces bad color artifact in
sc_web_browsing720p on slide change (wrong color
blocks appear in some areas).
