I'm using vc_dispmanx as a display engine and noticed the presence of vc_vchi_dispmanx library who looks quite close to vc_dispmanx.

Dispmanx seems to be a broadcom proprietary alternative to openGL, SDL, OpenMax, and so on ... It's a C library used in program such as raspivid/raspistill or pngview.

What is the difference / When should we use vc_vchi_dispmanx ?

I found more information at balena.

VCHIQ means Video Core Host Interface Queue and allows to communicate with the GPU through a kernel module/driver.
