I had to make the experience myself: in principle, the module fits all Samsung TVs, but there is one for flat and curved screens! (The contacts are minimally lower on the curved screen).
The modules only differ in the product number (both have the same name). When I bought it, the more expensive one was for the curved screens.

CI and CI+ differ in the function of the adapter and thus the possibilities, but not in the form factor. ^^

The CI or CI+ should fit

The module should fit all models
