It's not a dose independent response, if you eat only cholesterol (like only egg yolks for a month), you will find adding even more egg yolks does not increase the LDL, the excess gets processed into other nutrients or excreted. The feedback mechanisms in regulating LDL are very good, its just a optimization that food cholesterol can be used for circulating LDL, if you didn't eat any cholesterol at all your body would still make LDL.

More generally Cholesterol, and specifically LDL, is not a disease.

artificially lowering LDL is not actually good for your health. Its far more impactful to measure atherosclerotic risk directly with plaque imaging (CAC for example).
