Full 64-bit "True Stereo" 4 channel processing of impulse responses.
What does this mean ?
I'm familiar with B-Format (I used to won a Soundfield microphone)
.... hmmm ... having written that I realise I still regret having sold it - anyway ...
what does the "True Stereo" actually mean and what does '4 channel' processing have to do with it ?
I admit that the "4 channel"-part is slightly misleading in this context. 🙃 It has nothing to do with the four channels that are needed for 1st Order Ambisonics.
What it actually means to say is that the left and the right channel of the input signal will trigger dedicated, individual processing. In a stereo mix this would indeed result in four channels of IR-based reverb, hence the term "true stereo" (opposed to the formerly common approach of using the same IRs for the left and the right channel).
... but of course there will be five (or six) channels for each side of the input signal in case of a typical surround mix, or twelve in a full-blown 7.1.4 immersive setup.

A "true stereo" reverb has four channels consisting of the direct channel responses (L->L and R->R) and the cross-channel responses (L->R and R->L). Input sounds panned to one side will produce reverb output in both channels. This needs four channels to work. ... upscale for multi-channel formats! 😊
