sRGB or D1? Which is correct for scopes.

I have been using BCC for CC in premier pro and FCP.

The BCC videoscope is quite handy but I have always wondered why D1 showed more trace than sRGB. Most of the footage i use is from HMC150 and the GH3. I believe the HMC is 4:2:0 and the GH3 might be 4:2:2.

I normally grade CC in srgb but when i shift to D1 often my vectorscope pops illegal. I have not been rejected yet but ......

Which one is the correct one to use in a 1st pass CC workflow?
