This is a fantastic, detailed post that I would honestly recommend cross-posting to the JP thread if you ever feel like you have the time and energy. I feel that it would be well-received there. I also think male Au Ra get overlooked a lot in comparison to female Au Ra (although I do think female Au Ra very much do deserve the amount of attention they're getting in this case).
I also have a male Raen alt with the same face as yours and I disliked these changes too, lol, so I have some bias here.
In vein of that, I also wanted to share that, due to the pupil size change in male Au Ra--and how much smaller their eyes are compared to female Au Ra--the balance of their eye colors change quite a lot when you have limbal rings, when compared to the live version of the game.

Of course, I like the general fidelity increase in the eyes, and I think the gradient impression is very nice. However, in the current game, the color balance between the orange and yellow is more equal, with the orange color's larger spacial coverage being evened out by the glow of the yellow limbal ring. Meanwhile, in the benchmark, the orange is much more dominated by the yellow on all fronts.
That's not to say the pupil increase doesn't change the impression even without limbal rings, though. I personally feel that it does.
