Hey Shebbe,
thanks for sharing those examples.
Have you by any chance tried to grade under openDRT 1.0.0 ? I would be curious to hear some feedback from you.
Your examples remind me of two examples shared in this forum (here and here). I think in both cases the suggested solution was a LMT.
If memory serves, I think it was about logos (such as a red superhero one) and their invertibility.
Because of strong requirements such as hitting the display´s corners and invertibility, some compromises had to be made for the "rendering " of ACES 2.0. Also I don´t think I ever read smoothness in its design requirements (not in the dropbox at least).
Regards,
Chris
