No, the Hoge Veluwe actually is that far above sea level.

Definitely not the tree tops. That's also why it is called 'Hoge Veluwe' to begin with. (Hoge being Dutch for 'high').
The highest point is 110 m above sea level.

That's funny, I also went to Ede on the map (I have family that lives there.) The Hoge Veluwe is actually a mix of yellow and green, but the actual trees are yellow.
If you put the quality on Ultra the trees are suddenly visible as trees.
Also, looking at the scale: Ede is around 20-25m above sea level, the ground of the trees is around 30m above sea level, and the trees are around 45m above sea level. So the trees are around 10-15 meters tall, fairly consistently.
you can zoom in to individual tree level. I just did, and can confirm this data includes trees. Also make sure to adjust the colormap min and max to your area of interest. This dataset is the official height measurement of the Netherlands (of a few years ago), made with LIDAR. So it should be accurate to within a few cm.
I went to Ede, Gelderland (where I live), and while the city itself is mostly blue, the Hoge Veluwe just NE of the city is suddenly yellow (or is it green? I'm color blind), indicating that it's ~45m above sea level. That can't be right, the Hoge Veluwe is on the same level as Ede. What am I misreading?
Edit: I think I understand what's happening: the land immediately east and north of Ede is forest, so I guess the increased elevation in the point cloud is trees.
