Where is control point data stored?

[Bud]

Regarding control points:

• Video: Suppress symbol effect in ArcGIS Pro
• Introduction to control points

Where is the control point data stored? In the SHAPE column vertices in the GDB FC? In the CAD blob in Oracle SDE.ST_GEOMETRY?
Is control point information accessible programmatically through Python, SQL, etc.?

@Bud I like to consider control points similar to vertices with a special designation. They are stored as geometry attributes and you can convert a control point to a vertex or a vertex to a control point.  Note this is a newer functionality introduced at Pro 3.1. I found the SDK reference here: https://pro.arcgis.com/en/pro-app/3.1/sdk/api-reference/topic1519.html
