I can only speak for what I have seen in the US..but it seems to me that a large portion of the SUVs out there are really just minivans with different doors in the back and a slight suspension lift. Especially ones like the VW Atlas and comparable. Not to mention the living room sized vehicles like the Toyota Sequoia and GMC Yukon. Most of the larger ones have 3 rows and essentially the same design internally. If you squint hard enough and imagine sliding doors on the sides there is very little difference.

People seem to buy way larger than they really need also...but that has kinda always been a thing in the US.

There were some weird but large benefits to manufacturers for SUVs over minivans (didn't count against fuel economy standards, based on less expensive platforms). Those are mostly gone but the scale and preferences that they generated have at least partly led to the SUV takeover.

An interesting fact is that the first gen US Honda Odyssey minivan completely lacks slide out doors commonly associated with the vehicle type.
