Why does The Expanse Season 4 feel like a busted CGI pipeline from the old Model QFX-3 set?

Finished my marathon of The Expanse Season 4 around 2 AM and I'm still fuming. The narrative is solid, but the visual side feels like the show fell off a cliff and landed in an outdated CG rig.

• The Martian landing sequence uses the same Model QFX-3 texture mapping we saw in early 2015 sci‑fi shows. The anti‑aliased edges are missing, and the grain filter looks like a quick post‑process hack.
• Interior shots of the Rocinante now have mismatched depth cues. The camera rigging seems to have skipped the motion‑blur pass entirely, giving a jittery look that pulls me out of immersion.
• Color grading has regressed to a flat LUT that was apparently salvaged from an abandoned pilot. The subtle teal‑orange contrast that defined the series is now replaced with a bland teal‑green wash.

I get that budgets shrink after three seasons, but a half‑second flicker on the thruster particles should be a solvable issue. I've tried digging through the official behind‑the‑scenes clips, and none of the VFX supervisors mention an upgrade from QFX‑3 to the newer VFX‑Pro 7 pipeline. Am I the only one who's noticed this regression, or am I being overly critical?

Looking for validation, theories, or any insider info on whether the visual team had to cut corners. This isn’t a petty complaint—I invest time and emotions into the show. If you’re also feeling the same disconnect, let’s hear it.
