The difference between ICD and IPD is what makes the following images not life-size to me. I’ve found this interesting dataset to illustrate this: 2005 Stereo Datasets
Try this: cross your eyes, until the two squares align, and focus on the middle image

Do they look life-size to you? Bigger? Smaller?
Is the perceived depth life-size, bigger, smaller than expected?
Here is for example with objects, which we have an intimate knowledge of the size:
- cross eyes on the first pair
- compare how the yellow voltmeter seems maybe bigger in the bottom pair vs the top pair.
