RT does NOT have a dual-illuminant profile for both A6000 and A6500 - only A6000:
For A6500, there is only the basic DNG color matrix.
Note that in another discussion somewhere, there was evidence that C1 is doing some really weird things with colors in their profiles:
I own an A6300 and A6500, so now that things are calming down, I MIGHT be able to submit to @Morgan_Hardwood the ColorChecker shots needed to generate DCP profiles for those cameras.
MIGHT being that around here, “cloudless noon sunlight” is extremely rare in winter. We’re under a winter weather advisory so I don’t expect to see unobstructed sunlight for a few days. On the other hand, I have two days of work remaining before I hit “use it or lose it” for my vacation days, so I’ll have much more lunchtime availability for camera profiling if the sun ever comes out.
