sun shine details

I don't know if this quesiton is okay for here to ask.

I have a received a cg shot which has the sun shine ray, it's very bright, but i can see the details in the sun under the stardard computer screen. when I convert it by using the liner to log conversion and put it back to my log scene of baselight, also put the lut: I cannot see the details in the sun shine, does anyone know how to do this in DI process.

I think the cg artist should use my lut to view their work while making the cg shot.

Thanks.
