Steam Deck Sale Price Refunds?

A post on Reddit indicates customers who purchased Steam Decks immediately prior to them being discounted in the just launched Spring Sale on Steam have been able to successfully petition for refunds. This is unconfirmed, but there are reports from users saying they've received the price difference back as a Steam Wallet credit. Word is:
If you bought a Steam Deck recently just before the 10% off sale, Valve is offering (as an exception) a Steam Wallet credit for the difference in price if you open up a ticket.
