Both of the universal remotes I have to hand decline to learn codes from two audio devices I have been trying recently.

The remotes are old: MX500 and Pronto.

The devices are new, current models of Mark Levinson and d'Agostino.

Have the coding standards used by remote controls changed recently such that old learning remotes may have difficulty learning them?

It's possible those devices are using some abnormally high frequency (companies have done that in the past for no good reason - often high-end brands), although the Pronto in particular is a good learner (do make sure you're pointing at the right end - the learning eye is on the bottom, not the front).

Learning remotes don't necessarily have to know anything about what they're learning - they just capture the frequency and series of pulses that they see. The very first learning remote ever made in the mid 80's (GE Control Central) will still learn codes from a modern Blu-ray player using a code format that didn't even exist back then - so long as its frequency is in the ~40kHz "standard range".
