A sorcerer with the Shadow Magic origin has a feature called Eyes of the Dark, which states the following (XGTE, p. 51):
When you reach 3rd level in this class, you learn the darkness spell, which doesn't count against your number of sorcerer spells known. In addition, you can cast it by spending 2 sorcery points or by expending a spell slot. If you cast it with sorcery points, you can see through the darkness created by the spell.
A Ring of Spell Storing (DMG, p. 192) states:
This ring stores spells cast into it, holding them until the attuned wearer uses them.
Any creature can cast a spell of 1st through 5th level into the ring by touching the ring as the spell is cast. The spell has no effect, other than to be stored in the ring.
While wearing this ring, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell attack bonus, and spellcasting ability of the original caster, but is otherwise treated as if you cast the spell.
If a sorcerer cast darkness using sorcery points as per their Eyes of the Dark feature into the Ring of Spell Storing, then when they later "released" the spell from the ring, would they be able to see through the darkness as per their Eyes of the Dark feature?
(Bonus question: what if the ring was used by someone else; would the sorcerer who cast the spell originally still see though it, even though someone else "released" the spell? This is just out of interest, though; the main question I care about is in the case where the sorcerer uses the ring.)
I imagine one could argue yes, because it was originally cast via sorcery points, but one could also argue no, because of the technicality of the ring's description saying "but is otherwise treated as if you cast the spell", or something like that. Which is it?
