No, you would not be entitled to any compensation. You were marketed and sold a Delta One seat, the class of service is still the same, Delta makes no distinction across aircraft. While it sucks, this is what happens when airlines don't have fleet consistency. In an ideal world, there would be consumer protections for this and Delta would be held responsible for marketing certain products and doing swaps.

However, anecdotally, I have seen stories of people reaching out about this and allowed them to switch flights.
