Applying LUT in Photoshop

V-Ray V-Ray for 3ds Max Issues

Maybe a dumb question but when i apply a LUT file in PS through colour lookup it seems to come in differently to VFB LUT.

The closest i get is applying it with soft light / hard light in PS.

Is this correct ? or am i doing something wrong ?

if the LUT is saved from VFB than it works best on 32 bit files. 16 bit float is not that good in that regard.
still most often than not it does not look 100% the same, PS is weird with LUTs.

Thanks - i didnt think VFB saved the LUT as yet ?
