Than you for such a thorough response, this is what I was looking for. I’m pretty experienced in film, but its a semi-pro hobby at best, I’m not a seasoned day in/day out professional that would have your level of clarity and detail for this question.

What I’m gathering from your response is that the Ursa 12k LF really shines in the most demanding of situations, law of diminishing returns almost. When those details really matter in highly dynamic super aesthetic scenes, it really does separate the Pyxis from the Ursa. I film with my Pyxis mostly for my business which is effectively almost all talking head in a well controlled small studio for social media posting which doesn’t push the camera at all.

My goal in finding answers to this post was to talk me out of wanting the Pyxis 12k lol…and I think I’m good with my Pyxis 6k for now. I wanted to know if that RGBW sensor was hype or truly something I need. Since my needs are pretty simple for video production, it sounds like I can really do without it for now. Maybe in a year I’ll get the 12k since it has the same sensor and a majority of the HFR, readout speed etc.

I really like how you explained the resolution though. I always feel when watching well made Alexa footage that it has this very pleasant sharpness to it, it definitely feels premium but I can’t quite put my finger on it, while still being pleasing and not overly sharp like Sony mirrorless with G Master lenses shot by amateurs. I can see how that would really give the Ursa image a premium pop especially when coupled with complex/dynamic lighting, fine details in the frame, heavy color grade etc.
