Thank you, i've seen that calibrations (i'm on the same thread

but noone answered me :/), they are for SDR pictures
I think the only solution is to activate color enhancement and boost color up at this point. Today i'll try to call Philips support center and share with you what they'll say!
Update: Philips told me that this TV doesn't support HDR XD! After a little arguing, they told me to send them some videos, i'll keep you update.
Meanwhile, i found out in a forum that the problem is due to the NVM Firmware that need and update (through philips customer service), but it's difficult to talk with them..
