Legacy is a bitch.
It took a long time to move from the old component input over to HDMI. The main thing that drove it was the SD to HD change. You needed HDMI to do 1080p (I believe, IDK that component ever supported that high of a resolution).
Moving from HDMI to display port is going to be the same issue. People already have all their favorite HDMI devices plugged in and setup for their TVs.
You need a feature that people want which HDMI isn't or can't provide in order to incentivize a switch.
For example, perhaps display port could offer something like power delivery. That could allow things like media sticks to be solely powered by the TV eliminating some cable management.
The legacy issue is even worse than that. I have a very new Onkyo RZ30 receiver and it is all HDMI with no DisplayPort to be seen. So it is the whole ecosystem including the TV that would need to switch to DP support.

It already does. A guaranteed minimum of 1.65W at 3.3V is to be provided. Until very recently, HDMI only provided a guaranteed minimum of something like 0.25W at 5V.
It's not nothing, but it's also very little to play with.
5W is what I'd think is about the minimum for doing something useful. 25W would actually be usable by a large swath of devices. The raspberry pi 4, for example, has a 10W requirement. Amazon's fire stick has ~5W requirement.

Sure. But it's ~6.6x more than what HDMI has historically guaranteed. It's pretty obvious to anyone with two neurons to spark together that the problem here isn't "amount of power you can suck out of the display port". If it were, DP would have swept away HDMI ages ago.
