There seems to be no attempt to balance the channels for the increased red sensitivity.
This separation, highlighted on the left, is unusual:

I find the EOS Ra to be surprisingly noise-free at higher ISO settings. The sensitivity to magenta is definitely there as a result of the IR-cut sensor. Hence the images of re nebulae are strongly saturated. Overall, it's an impressive camera that needs no IBIS but can still be used for terrestrial photography if you're willing to edit your images. The only thing that proves challenging is processing skin tones. But that's to be expected from an Astro-specific camera.

I've been incredibly impressed with the EOS Ra's performance. I look forward to seeing what it will capture with longer exposures and longer lenses when used on an EQ Mount to track the sky. The images it has captured for me so far - with merely 6 second and sometimes 10 second exposures - have been extraordinary.

I did a comparison between the Ra and A7r3 tracked.  It was not mind blowingly better but I preferred the colors of the Ra. The sony was better at capturing light with less noise though.
