I hear what you are saying, but please let me explain. In my view, Nissan has very good mechanical and driveline engineers, and I have had 4 Nissan vehicles so far, with the latest being a 2015 PathFinder with a CVT and the VQ35 engine.
The procedure you speak of is not a CVT fluid analysis, rather it is solely a computation by the computer. I have yet to see any Nissan Service Writer instruct a Nissan mechanic to take a CVT fluid sample at various mileages for routine mechanical checks.
Besides, a Nissan Service Writer nor a Nissan mechanic is qualified to interpret a real fluid analysis.
The computer makes various assumptions based on inputs from driving style, ambient temperature, and various sensor inputs.
The only feedback from the CVT to the computer is RPM, pressure and temperature sensor values.
The computer does not have any sensors that can analyze the viscosity, elemental, or oxidation properties of the CVT fluid.
The CVT fluid life prediction is based primarily on two factors: Warranty coverage and lowering the cost of In-Warranty replacement for the Manfacturer and the Dealer.
The CVT fluid life prediction is not based on providing any reliability promises after the Warranty period.
The vehicle is yours to do what you wish and no one is telling you what to do.
I hope this helps with your future decisions regarding fluid changes.
Lastly, using actual fluid analysis, I have won a number of claims against manufactures and dealers for some clients, and one claim was mine.
