Movies for broadcast delivered on DVD are indeed -20 dBFS.
For DVD it's probably creeping closer to -14 or worse (twice as loud average level).
For trailers, it's quite common to approach 90's CD levels (K12 or worse).

This is not correct.
In the states, a movie is mixed in a calibrated room where -20dBFS Steady State Pink = 85dBC across the front, 91-2 dBC (technically +10dB of in-band gain above the fronts) from the Sub and 82 dBC from the surrounds.
From there, it all by ear (with maybe some nudging by the director).
In EBU countries the reference is -18dBFS and corresponds to electrical level of 0dBu

A Theatrical Screened Trailer, in Holland, in Europe, in the States MUST conform to a loudness not exceeding 85 dB Leq(m).
If the movie goes to broadcast, it will be subject to the deliverable specifications of the Network. It may mean that some peaks have to come down, and some average level may have to come up.
A few things not left up to the imagination.
When it goes to DVD, there are no
RULES, there is no calibrated playback venue. Except, calibration changes to be equal values all around. SOME movies and trailers are simply transferred. MANY are "remixed" by a DVD house that specializes in this sort of thing. (Mi Casa and POP come to mind). They often end up louder.
I would align your room so -18dBFS pink = 79 SPL (C weighted slow) all the way around,, no +10 on the SUB. Then I would master it by ear. I would also check it WITH BASS MANAGEMENT as just about every one at home has a bass managed system. The reason for 79 is you are not in a theatrical sized room. But I would master it LOUD. But I won't give you an RMS. Don't be afraid -.03dBFS Just make them sound good (and kinda loud).
Music and concert DVD's are often mastered to sound good and use the full scale.
