Yes, Photographic 1 (i don't use other two) works great on many bright low contrast scenes, but are unusable on darker, more contrasty scenes, as it gives so massive contrast, that is impossible to tone down, but to reduce lut opacity to 0,2 - 0,4 at which point there's little sense to use lut at all. Also, quite often i find that it's very hard, nearly impossible to recover highlights when using dubcat's luts. It just leaves big flat dead areas with no details. But in scenes, where it works, it works just great.
By the way, when using these luts, more than ever i wish that Corona VFB would have some controls for midtones.
That is my highly unprofessional impressions.
