Dietary cholesterol is very directly correlated with blood cholesterol levels. You can feed someone cholesterol and directly watch their levels spike. But your body will clear it if you give it time which is why your fasting cholesterol may not show this if you have naturally low levels.
But during that window if time that cholesterol is active in your blood it's not doing you any favors. This is why heart attacks very often follow shortly after a meal.
Note that dietary cholesterol only correlates to blood cholesterol in about 40% of the population. And even within that group, "Even though dietary cholesterol modestly increases LDL in these individuals, it does not seem to increase their risk of heart disease" (https://www.healthline.com/nutrition/dietary-cholesterol-doe... -- emphasis is mine)
You're talking about baseline or fasting cholesterol. You can do the experiment of feeding someone a high cholesterol meal, then immediately take a blood sample and see the spike in their blood. This has been confirmed many times.

This is not true. In fact, I doubt dietary cholesterol has any affects on blood cholesterol.
Source: eating >= 6 full eggs daily for years; have 8 pack; blood work always on point.
And also I've done the same exact thing you mention and it didn't affect my blood levels at all.
