Thanks for sharing that link. The categories suggest that this system is mainly used to give priority to certain kinds of vehicles. Public transport and emergency vehicles already had a system to turn lights green, so this seems like an addition to extend the system to "milder" priority vehicles like construction without giving them access to the previous system.
The location of the lights doesn't exactly point to usage by cyclists.
As far as I know, almost all traffic lights in the Netherlands work with magnetic sensors under the road for presence detection. Then there are a few optical cameras for congestion detection at specific intersections.
The magnetic sensors don't pick up ultralight or carbon road bikes, but bikes usually have an additional push button anyway.

It depends on the city, but unless you're on the highway or about to enter one, a traffic light here can be assumed to serve bikes.
I found that link a few years ago thanks to an app I used when I went to university: https://www.enschedefietsstad.nl/enschede-fietst-app/snel-gr... The municipality has an app that will integrate with the iVRI system to have traffic lights turn green faster for bikes. It doesn't do anything for cars, it's built purely to try to convince more people not to travel by car.
Of course, iVRI data providing information about incoming bicycles don't automatically reprogram traffic lights to give them priority. However, the information is available. I've had the Enschede app trigger a "this app requested X green lights during your ride" popup in other cities; I'm pretty sure it's just an iVRI integration, not one restricted by a specific municipality.
