But both models say they have Bluetooth, wired, and 2.4Ghz connectivity. They both include a USB-C 2.4Ghz dongle, and both explicitly call out Bluetooth as a way to connect to certain devices, so must both have transmitters for that, too. The “Wireless” version calls its wireless protocol “8Speed” and lists its low latency as a feature, but the “Bluetooth” product page doesn’t say anything that would imply its non-bluetooth wireless is different. It merely doesn’t discuss it.
The only real hardware differences I’ve been able to discern so far are that:
the “Ultimate 2 Wireless” version shows colored labels on the ABXY buttons, while on the “Ultimate 2 Bluetooth” version the labels appear to be white.
the “Ultimate 2 Wireless” comes in black, white, and purple while the “Bluetooth” version only comes in black and white.
the “Ultimate 2C Wireless” comes in mint, peach, green, and purple while the “2C Wireless” version comes in blue, pink, and dark blue.

It looks like they’re each compatible with different devices maybe
I have 2C wireless and there is no Bluetooth to be found.
