Well, I could be completely wrong but I think it’s likely that Rogers LUT has it’s origins in profiled film data, especially In it’s colours. Many high end facilities will be basing their propriety LUTS on films colour and contrast response as a starting point. I’d also add that while you say Rogers LUT doesn’t shift hues I think if you look at his imagery carefully and compare it to just adding contrast and saturation to a LogC image you’ll find it’s pretty different. The colour response is different, it’s very different for example in comparison to arri’s standard rec709 lut. Therefore how colours saturate and the hue that they are has been manipulated. If you think about it, every LUT basically is shifting hues/colours somewhat. The LUT is taking a colour input and shifting it to a chosen colour output. The colour is being shifted in hue, saturation and luminance. If you look at for example the lips of people in Rogers LUT you’ll notice that they don’t appear like they do in Arri’s rec709 lut and this is because the colour of eg the reds/pinks has been manipulated inside the LUT, likely being more desaturated in comparison with the standard Arri lut. Also, look at the greens in Rogers LUT, much more natural than arri’s rec709 lut which as you point out are saturated and garish. Personally I think the LUT is really important and it’s kind of like a film stock. The LUT defines the hue, saturation and luminance of colours, along with the overall contrast of the image. If you have for example bright and garish reds and greens in your LUT it can have a profound impact on the feeling of an image. Try looking at reds that skew to a bright magenta compared with reds that when saturated reduce in luminance and shift more towards a darker blood colour in comparison. Big difference. Personally I much prefer the deeper darker blood reds than bright garish magenta reds. I feel I’m only just starting my journey of really looking at the colours I am seeing and developing a sensitivity and understanding for them and a taste for what I do and do not like. We’re so used to colour because we have seen it every day since we were born that I feel it takes a strange re-awakening to begin seeing them afresh and being able to analyse and understand what we are seeing, what we like and why. I think It’s pretty fascinating
