The interesting part of underfloor heating is that it is not the hot air that warms the room. It is the radiation from the floor. Smth like 10w/C/m2. And the heat profile in the room looks much better. For example https://www.researchgate.net/figure/An-example-of-vertical-t...

Well, the infrared heating warms the air which warms the room if you want to be pedantic.

Unless you're losing heat through the floor I doubt that temperature difference between the floor and ceiling is accurate with a radiator system, perhaps if you measure it 30 minutes after you turn on the heat, but throughout the day the temperature should be mostly consistent throughout the room unless you're losing heat through the floor.

I think the air is almost transparent to infrared.

The underfloor heating uses a low temperature; the floor is ~24 C. There is little air movement because there is a very small temp gradient. With a radiator or a stove, its temperature is much higher, prob > 60 C. So you will have a column of hot air that rises to the top of the room and stays there. And at the floor level it is much colder.
