yest, that is what I've done after further digging.

I've done a second encode with x264 rgb for keeping the master, I only needed YCBCR for the final 10 bit encode.

Well, Premiere interpreted the color matrix correctly so lost information was minimal.

BT2020 is for depth 10bit files and currently isn't recognized by most programs only TV.
sRGB isn't recognized by most programs.

sRGB would be interesting for the master, but then again, premiere doesn't export it Afaik so taht would only add another conversion and more rounding losses in the process.
Thanks for all the help, I was able to attain virtually imperceivable loss in color information just by using ConverTToYV24 (matrix="rec709")
Here a sample to anyone curious.

Lossless in this case is qp0 veryslow no bframes x264 yv24 encode, but I'm in the middle of doing a RGB x264 encode right now as a V2.
