The original pixel color in the PNG file is R:153 G:255 B:153.
On the 10.4 machine I get back R: 0.6 G: 1.0 B: 0.6
On the 10.2 machine I get back R: 0.53 G: 1.0 B 0.53
I understand this is being color adjusted by the system but I just need the raw values with nothing adjusted in any way.


You mean on 10.2? Well, that might just be a bug.

The values reported from 10.4 are without any adjustment. 0.6*255 = 153
