Hi, let me explain,
Clearview is a intelligent algorithm which applies microcontrast in such a way that the haze, lack of blacklevel, is less visisible.
And by concentrating on edges it sharpens the color change edges at the same time giving a sharper look to enhance lost sharpnes due haze.
These two actions are given you that saturated and clear and contrasty sharp effect.
In full view you see the spread microcontrast acting as adding blacklevel creating the less hazy clearer view but NOT the sharpening effect on the edges.
This you can preview at 70-100-400% or after export in your jpeg. (which can have a negative effect when it’s oversharpenend and causes moiré on my tv for example.
I can send your some examples if you like.
Edit:
Blacklevel is near 0 black. And contrast is basicly saturating a color by lowering lumination. Lumination at level 0 is black. Be aware that blacklevel is not exactly the same as microcontrast. Blacklevel attach the histogram to the left and does no sharpening on edges wile microcontrast is a sharpening tool.
