According to the people who have looked into this matter, because they wanted to compare the dynamic range of digital cameras such as the Reds and the Arris with traditional movie film cameras, 35 mm film has approx 14-15 stops of dynamic range and 70mm film has closer to 17 stops, IIRC.
What that means is that blu-ray SDR is way below what Casablanca, for example, was shot in and capable of showing or displaying.
HDR 10 and even more so 12 bit Dolby Vision with dynamic metadata, is much closer to the actual dynamic range of 35mm and 70mm film stock.
Having said that, of course there are all sorts of other variables such as the brightness of the projector/tv and it's contrast ratio, viewing conditions etc which also need to be taken into account.

How does that equate to the actual contrast of the film stock we see in theatres, which is typically not a great deal more than 2000:1?

I also seem to remember seeing it said here that the cameras can only capture around that number too.

I have no idea, to be honest.
I do know that the quality of a film print varies greatly with age and how well the projectionists maintained the projector in each theatre so there are a large number of variables involved, even if the theatre did or does try and keep to THX or industry standard recommendations.

Yeah, print quality suffers a lot from the original negative - bulk release prints tend to lose some resolution in the process, and a few runs through the projector can add wear and tear, leaving us with a lot less effective resolution than with digital.

I believe celluloid is in the region of 15-20k:1 captured contrast ratio with 14-15 stops of dynamic range as mentioned above.

A camera like the Arri Alexa can capture even more contrast.

I used to have a link which broke down various cameras but can't find it right now.
