In a word, no (or possibly maybe). Mirabel certainly doesn't receive any overt gifts at the end of Encanto, but she does seem to have the same powers that Abuela manifested, e.g. sustaining the miraculous valley and providing the house (and her family) with magic.
In the tie-in novelisation we learn that her door, and the room behind it has remained entirely mundane. If we assume that having a magical bedroom door is an indicator of magical powers, having a non-magical bedroom door is an indicator of a lack of magical powers.
The door that was so plain and ordinary is now magnificent. Isabela's flowers outline the frame. Luisa has added bright, strong colors. Antonio's animals are represented. There's a rainbow that could only be from Pepa. I see a little theater, perfect for performing rats... thanks to Tío Bruno.
I open the new door, and my room is more beautiful and fantastical than I ever could have imagined. You would never know that it used to be a plain nursery. A vine grows above the bed like a canopy. A chigüiro is curled up on my pillow like a stuffed animal. A heavy bookshelf is loaded with books. A cup of hot chocolate and a plate of arepas steams on the table. Everyone in my family has added a little something to my room.
