Generally I categorize briyani in 2 categories. Restaurant and normal hawker/coffeeshop/Indian Muslim eater.
Restaurant and I mean the really good Indian ones will generally have the better briyani. Best I ever had was from Rang Mahal. But that's pricey. A slightly less pricey would be Islamic Restaurant. That also quite good. But not all expensive and pricier restaurants have good briyani. You'll need to read reviews beforehand to know which cmi.
But for the average person - the second category - I find that if you see a Malay or more Malay leaning type of Indian Muslim (like our Halimah), they make the better ones. Like Rafi Ali's dad's one. Almost always all the Indian Muslim restaurants cmi. It's as you said, just coloured rice, and chicken or mutton curry put on top of it.
So this guy's one looks more like the ones the Malays would cook, really dum briyani. Actually the other way round, the Malays copied the Afghans, Banglas and Pakistani way and modified it a bit.
However that said, there is a difference between Bangla and Indian style as pointed out to me.
So it's something on my bucket list.
