Judgments/public records fall into your "payment history" portion of your score (a little over 1/3 of your FICO points come from this portion).
Depending on what else is going on in your "payment history" section, removing them may not have had much effect (as reflected in the underwhelming rise in score from having them removed). Late payments, missed payments, the number of accounts you have which show even one of these, foreclosures, repossessions, chargeoffs, collections (open or closed) - all of these affect your "payment history" section's score, in addition to judgments. The age of each lessens its affect too, so if your judgments were older than a couple of years, their effect was already diminished.
Anyone pulling your credit - whether it's Experian's monitoring service (CCT), a third-party score/report provider like myFICO, one of your current lenders, or a prospective lender - sees the same information. They take the information they find and put it through one of a dozen FICO scoring models (FICO 8 being one version but certainly not the only one out there) to spit out a score. For example, if you are looking for an auto loan, lenders considering your application may apply auto-enhanced FICO 8, or regular FICO 8, or mortgage FICO 5, or any of the available versions they like; each of these likely yields a different score on the same file. The file remains the same, but may yield slightly different results depending on the lender's calculations.
