You are quite correct. Very few so called 4WD vehicles have REAL 4WD. As you say Landy family, Landcruiser & Subaru together with Mitsubishi PHEV, have real 4WD.
Softroaders such as Honda CR-V, HR-V and all Skodas use the Haldex system which is fully automatic. If a front wheel slips by about 1/8th of a revolution the rear wheels will be brought into play. The driver has no choice. No Hi-Lo ratios. The Haldex system is not bad at getting you out of a wet, grassy field, but for serious mud plugging you need proper 4WD.
