Don't think Watame used hers yesterday, but she does pull it out when she plays Smash Ultimate.
I think most Holos up to gen 4 has used their 3D model at home at least once. Can't recall Fubuki, Mel, Haachama, Shion, Choco, Flare, and Kanata using theirs though.
They roll out updates for these models to use at home. Most recent model I can think of is Towa's who uses it for Ring Fit Adventure.
Sora, Miko, and Roboco have been using a version that tracks their hand movements.
