If the film is of a big international distributer, chances are 99% that the film is not a true 24, but instead 23.976. I don't know why, since the digital age has released the studios of the weird uneven frame rates, yet here we are. But the difference between 24 and 23.976 is pretty negligible, the difference is not something you will notice whatsoever unless you have them run side by side for the entirety. I would prefer it to not have 23.976, but I don't mind it.
And PAL DVD's rarely use any pulldown method, because a single duplicate frame you will absolutely notice throughout because it would create a super noticeable stutter. I have a old DVD of 13 Going On 30 that did that stunt, and good lord I wanted to strangle the person that went over that transfer. The stutter was absolutely dreadful! No thankfully what nearly all PAL DVD have is PAL speed up, what they do is speed the film up by 4%, that gives you the entire film with a nice evenly 25 frames a second (or 50i if you want to be picky). The downside is that you speed it up and there's a difference in pitch if they don't correct this. Which most do, but some don't. I don't have to many issues watching DVD's these days, even not on my 4k TV. They look compressed, sure, but the film can still be watchable without to many issues. Well unless it's a musical, because the speed difference absolutely grinds my gears to no end.
For shits and giggles, I checked out a bunch of my discs just now, both from European and American distributors just to illustrate my point. Film with a * were produced in counties other than the US:

So basically, of all content I own that are 24 frames, they're nearly all BFI (British Film Institute) releases. But three of those are silent films and were recorded at a slower frame-rate, so they're a bit fast and stuttery since there are duplicate frames. Eureka seems to release nearly all their stuff in 23.976, but 'La Planete Sauvage' seems to be the expection to that rule for some reason.
Absolutely everything else seems to be 23.976. Now this is a small sample size of what I own, but I went for a bunch of different distributers from a variety of European countries (UK, Dutch, Italian, German, Spanish and others) both big and small and both EU and US (though I don't have many US releases). Unfortunately, it is what it is, but what ya gonna do. I have no experience with the La Séance releases, but I wouldn't be surprised if they're 23.976, it's just how it's mostly is. Even Criterion, a company that's all about presenting a film in the absolute best way possible and cost a ton of money, don't bother with it.
Long story short, we'll see, only time will tell :p
