EXR textures with negative values in Gamma space

Hi,

In my shader I'm using EXR textures to morph my mesh, morphing looks like this:

and the texture which stores every vertex position over time looks like this:

Of course, some of the values in this EXR texture are negative. It works fine in Linear but when I'm using Gamma, the shader cannot offset vertices on negative values. I think this happening because for some reason Unity can't see the negative values in EXR texture in Gamma mode.

So, is there a way to somehow fix this?
