Is Ilford MGIV the only 3-emulsion VC paper?

Does anyone know of Ilford Multigrade IV the only paper with 3 emulsion components to generate the variable contrast range? By looking at the contrast calibration numbers for the RH Deigns Zone Master meter, it seems like Ilford MG IV definitely has a wider contrast range than most (if not all) other papers. I've been using Adorama RC glossy for regular (non-exhibit) printing, but it doesn't seem to have the same contrast range as Ilford MG IV at either the high end or low end, That makes me think it may be the older 2-compnoent emulsion type. Kentmere VC paper also have similar calibration numbers to the Adorama.
