At these different brightnesses, the images look somewhat different
in a non-adapting way that does cause colorists to make errors.
Specifically, bright colors have increased saturation because the 
primaries
are brighter and 'further (up &) out' than the dimmer version.   This 
especially
effects face tones which might appear too flushed.  In general though,
an image that looks just right when set at 22fL, looks overly 'hot'
at 35fL,  while conversely, an image that is right at 35fL looks 'weak'
or desaturated slightly at 22fL.
