You mean 96% or 96/255? I've made one of each.

Unfortunately photoshop doesn't use blends like "Add", let alone A(1-B)+B. 
So I've had to use a multiply layer using the inverse of the greyscale (PS 
doesn't seem to have an invert option so I did a difference with white), 
with a "screen" layer that roughly looks additive.

What were you hoping it would look like? All you've done is effectively 
desaturate the brighter bits, which looks pretty dull.
