Nissan CVT Fluid Change

Just bought a 2011 Nissan Murano with 99k miles. It drives great and I can’t feel any problems with the transmission but I have heard these can have issues. This one is extremely smooth currently. The CVT Fluid looks good but is slightly on the lower side of the acceptable range. I want to do everything I can to prolong the life of the CVT but I’ve heard mixed reviews on changing the fluids if it has never been changed. From what I can tell through service record it has not in this car. I am considering just a drain and fill and maybe changing the internal filter. Will this be good for my transmission or still it up and make it fail sooner.
