Alcohol is available in hotels and also licensed alcohol shops for which you technically need a permit (though I don’t think we ever got one).
I’m not sure how religiosity would express itself, really, given that Emiratis are less than 10% of the population of Dubai now.
One thing that’s changed and that is indicative since we lived there is the weekend. Traditionally, the weekend of a Muslim country was Thursday and Friday (Friday being the holy day for mosque attendance), but that messed with the working week being out of synch internationally, which damaged business, so when we lived there in the 2000s, the weekend was Friday and Saturday, and the working week started on Sunday. Now weekends in Dubai are Saturday and Sunday, to bring it fully in line with the working week in the world at large. So I suppose that’s an example of commercial practices winning out over religious ones.
Ramadan still, involved no one, including non-Muslims, permitted to eat or drink in public during daylight hours, and hotel meals and some cafes and restaurants being served behind curtains/screens, but if you went into the loo in a mall during the day, there was a lot of munching coming from cubicles. The crazy driving as thirsty fasting people with low blood sugar sped towards iftar at dusk was definitely a thing.
It certainly didn’t strike me as in any way a devout place when we lived there. It’s a consumer paradise. The ‘Christmas’ equivalent is the Dubai Festival of Shopping.😃
