No.Taking price completely out of the questions I'm curious as to whether having too much RAM can cause any negative effects?

If the RAM isn't in use it remains in a low-power state that probable won't much affect battery life.
And it's not like RAM chips can be selectively disabled at random. If your system only uses 10GB of 32GB RAM it does not mean that the rest 22GB are turned off or something.
In use means storing data. The way it used to work is that RAM chips not in use were kept at a low-powered state, but since DDR4 doesn't have that the same way, I'd guess the OS just powers off RAM chips not in use. You can't power down part of a DDR4 chip as far as I know, but you can power down a whole one. There are a number of chips for 64GB.Define "in use". RAM is a volatile memory storage, it needs power to sustain its content. And it's not like RAM chips can be selectively disabled at random. If your system only uses 10GB of 32GB RAM it does not mean that the rest 22GB are turned off or something. It is true that RAM needs less power to sustain the data than to change it, but the question is how much less exactly... DDR4 is not necessarily optimized for idle power consumption, unlike LPDDR4 and friends.
That's exactly what it means.
LPDDR4 supports partial array refresh. Power gating turns off unused portions of the DRAM PHY. The power draw argument is an old wives tale that fools only the uninformed.
