You can find YouView boxes on eBay, or, if you would like a guarantee, on CeX.
YouView boxes since December 2019 have remained the property of BT, so the latest box, the Pro box isn’t available to own, even for BT subscribers. However, you can become the unregistered keeper of one 😛
The previous flagship box was the DTR-T4000, which can do 4K on suitable apps. Below that, the DTR-T2xxx boxes are all much of a HD muchness, though the DTR-T2000 box was YouView retail, and has a different form factor.
But YouView boxes aren’t Freeview Play either, and in fact don’t support some of the Freeview IP channels, so the Samsung may be closer to Freeview Play than a YouView box.
If you want an OLED with Freeview Play, then LG should be your choice, IMHO. The sweet spot is the 2023 C3, at whatever screen size you prefer, though there are some cracking deals on the outgoing 2022 C2s, which also have Freeview Play. But they don’t support DTS-X like the C3s now do, if that matters to you.
The G3 is gorgeous, but quite a price hike from the C3, and is meant to be wall hung.
We’ve just hung a 48” C2 in our bedroom, to complement the 65” GX in the lounge; when we want DTS-X, the GX soundbar will supply it 😛
