The answer is that it depends - and it really does. With Bollinger, I find that the RDs don’t necessarily get much better with age while the Grande Annees do and in most years I find the peak of a well cared for Grande Annee eventually tops the peak of an RD. With DP, the Plentitude (or Oenotheque or Late Disgorged) releases all develop very well after release. With Krug Collection, the wines also develop although I usually prefer a well aged original release. Complicating Krug Collection is that recent vintages are all late disgorgements, but going back in time, they were a mix of orginal disgorgement, later disgorgement, and recent disgorgement.
With many smaller producers or even some of the bigger ones, they will often do a recent disgorgement release just a few years after the original release (kind of like Bollinger does with the RD). When the original release of the wine has only seen 3-5 years of lees aging, I do think that you can find an uptick in quality with a later release, recent disgorgement that saw more lees aging (say 5-10 years). These seem to age nicely too.
You also have to remember that not all late release wines are always late disgorged wines or recent disgorged wines; many also see differences in terms of dosage, aging position, and/or closure for aging during the second fermentation (cork vs. crown). A recent example of a late disgorged, but not necessarily recently disgorged release is the Louis Roederer Cristal Vinotheque series. These wines see a lot more age on the lees than the original release before they are disgorged, but are then aged in the cellar post-disgorgement for many years before release.
You really have to go producer by producer as there is so much that you can do with the winemaking once the wine is in the bottle. The best reason in my book to buy any recent disgorgement or late release is for provenance. You know where the wine has been for many years. In most cases, smart money or the value play is to purchase the original release wine (assuming it saw enough lees aging) and cellar it yourself.
To generalize - If you are looking for an experience with a recently disgorged wine that will give you freshness, structure, and precision mixed with more bread, biscuit, nut based notes and usually a bit more dryness then pop the wine within a year or two of release. If you want the freshness to subside and the wine to relax a bit with drier, mineral, bread, biscuit, nut notes then cellar longer.
I am also a believer that there is an optimum time to disgorge a wine, but it isn’t always practical to do this or easy to figure out.
