I agree; it's my last Brian De Palma favorite movie.
Regarding the transfer, big disappointment because it's not better than the WEB 1080 release which I have grabbed in the past.
a X4 transfer would show better what we can barely distinguish from scenes to scenes : the use of "glow"/"halo effect" lens for instance to emphasize the dream in a dream sequences.
I think that when you know and live near Paris and hear the French dialogues, the movie is even more pleasing.
The Vertigo obsession (Rebecca is a blonde, a brunette, etc...) even from the spiral shot of the the plane reactor, the Blow Out/Up references, etc...
I think that Rebecca Romijn Stamos was the perfect lead actress for the strip tease scene in the backroom/bar scene (I like tall girls), her French (which is good even better and more geniune than the true French actors in this movie), Antonio Banderas gay-routine (that said, the hotel receptionist in Eyes Wide Shut is as good) when he visited her in her hotel room to find a floppy disk (when he knows how to be "sober" in Almodovar's "Pain and Glory", everything is "too much".
But we needed something too big to be true, even grotesque, bigger than Body Double, even for a dream- which we don't know if this is a dream in a dream, another fantasy-fetishizing movie like Body Double (one of my top favorite from this Brian De Palma's "path")
and there is even though a kind of fragility, sadness in the bathroom first scenes and some others, and I think that Rebecca did a good job. The piano version in the end of the Bolero is sublime.
I love the constant quotes or "inception"-inner-quotes- (like you- I love the long opening a clin d'œil (revenge?) to Impossible Misson with the variation of the Bolero, the use of split screen with every past B.De Palma's techniques (split screen, use of a setting to create a split screen (the commissariat scene for instance or the "
you known girls" pipi-chic-room at the beginning, the bad French actors and dialogue, the cat cameo, etc...)
I'm French, and it's now a testimony about Paris, with these shops (hum), the streets... you know that Brian was kind of addicted to some movies when he did Body Double and the "backroom"/bar scene is priceless with the (oh my god they already use an auto-tune at that time ?! ](*,) ) "
ça fait du mal, ça fait du bien" improbable song and with posters of Marc Dorcel infamous French VHS (you can ID now thanks to the HD resolution these posters) - I'm sure Brian saw these videos in Paris (me too).
Now, it's very old; 20 years ago.
I remember I saw it in theatre in France, with a theatre full of senior, old people Pensioners (like in Harry Nilsson's song "
I'd Rather Be Dead") who went to see the movie. Apparently the Pension organizers did not know what it was about - you could not tell with the French theatrical poster.
All were drooling from the kissing-robbery-luxurious scene to the end of the movie.

Me too, with my bib.
It makes me kind of sad; after Covid, this is a kind of
au revoir to Paris.
my favorite B.De Palma movies (and not necessary in this order) : Phantom Of The Paradise, Carrie, Obsession, Dressed To Kill, Body Double, Blow Out, Scarface.
