FX6 different LUT for base 800 and base 12800 ?

[Damien Dufresne]

Hello,

I used a FX6 in Cine EI mode in base 800 and base 12800.

All the proxies from the camera in base 800 and base 12800 looks good.

but for the XAVC-I files I need to use two different LUTs,  I can't use one LUT and the Lut s709 doesn't work well 

is it normal ?  maybe it's a Firmware to update ?

Thank you !
