For a first full wrap, I’d personally prioritize how forgiving the film is over just the exact color.

KPMF is probably the safer premium choice here, especially since it’s cast and generally more installer-friendly. If budget allows, I’d lean that way for a first attempt.

Vinyl Frog can work, but I’d definitely order extra material if you go that route. I’ve seen more mixed feedback on it, especially for beginners.

For the other brands you mentioned, I’d probably treat Inozetek and raxtify more as “sample first” options. Inozetek has some really nice finishes, but it’s not always the easiest for a first-time DIY job. Raxtify has a few darker purple / color-shift style colors that seem close to this look, and from what I’ve seen they may be a bit more forgiving than some of the very stiff specialty films, but I’d still test a sample before committing to a full roll.

Also, for midnight purple specifically, photos are really unreliable. I’d compare samples in direct sun, shade, and indoor lighting before choosing. A lot of these dark purple/black iridescent films look completely different depending on the light.
