Hmm - my current machine and/or eyes may not work properly - can you pinpoint the issue to me in those pictures you sent?

How did you create these TIFs? I sometimes see strange color artifacts just because of some display or screen grab issues. Where/how did YOU notice them? Playing the DCP? On a cinema/DCI projector?
