My bad. I was looking on a smart phone and didn't realize I only entered the white data.
Yes I do have the reference points AND the corrections. Now before I say what the reference and meter measurements were, let me ask this. I assumed that the plasma display used was not calibrated to Rec709 (or any) spec., as is indicated by the reference measurements not showing at spec. So, I thought the difference is all that matters. IF the display had been at Rec709, the reference measurements would have been at Rec709 and my meter's measurements would be off by the 'corrections'. As an example, the white measurement I did post was x = 0.309 for my D3 and x = 0.316 for the reference. Error is 0.007. So, I assumed that if the white point x had been where it belonged at 0.313, the reference probe would have shown x = 0.313 and my D3 would have measured 0.306, for the same error of 0.007. I did that with all the WRGB data and entered those into the matrices. All reference data were entered at Rec709 specs, and my 'measured' data were what they would have been, using the same measured corrections that would have if the display had been at Rec709. Was this incorrect to do it this way. It just helped me 'see' and understand where my meter was off relative to something I have some familiarity with. It also gave me an reference matrix I thought I could use to verify my matrix skills, such as they are.
So here they are:
MY D3 | REFERENCE | CORRECTION x/y
W .309/.335 | .316/.335 | .007/0
R .625/.337 | .632/.333 | .007/-.004
G .292/.601 | .298/.595 | .006/-.006
B .150/.066 | .150/.066 | 0/0
