For the colors: No you don't understand correctly. Please use the forum search I explained this with great details and examples at least 10 times.

For the "above" as "really larger as". The scaling uses the max from two dimensions. As most 1920x1080 movies are ripped with the black bars removed they are 1920x800 or something - so this 0% would always trigger the scaling and technically:

Code:

float scaleX = fabs(((float)m_sourceWidth - m_destRect.Width())/m_sourceWidth)*100;
float scaleY = fabs(((float)m_sourceHeight - m_destRect.Height())/m_sourceHeight)*100;
int minScale = CSettings::GetInstance().GetInt(CSettings::SETTING_VIDEOPLAYER_HQSCALERS);
if (scaleX < minScale && scaleY < minScale)
  return false;

if (g_Windowing.IsExtSupported("GL_EXT_framebuffer_object") && (m_renderMethod & RENDER_GLSL))
{
  // spline36 and lanczos3 are only allowed through advancedsettings.xml
  if(method != VS_SCALINGMETHOD_SPLINE36
  && method != VS_SCALINGMETHOD_LANCZOS3)
   return true;
  else
    return g_advancedSettings.m_videoEnableHighQualityHwScalers;
}

not lower means: larger or equal ... so even 1920x1080 will tick it. The default is bad. PR is pending: https://github.com/xbmc/xbmc/pull/9915
