That is what it looks like to me. The driver setup seems fine, this looks like a plasma SNAFU.
(and you wonder why I'm quite happy with kde3?)
Did you see anything concerning with the nvidia-smi output here by chance?
No, not really, but I'm no nvidia-smi expert. I looked at it and saw the apps that were able to utilize hardware accel using it, but many kde6 apps just weren't -- that points to a kde6 issue to me.
I *had* also enabled and started the nvidia.persistence service then powercycled.
No better.

This shouldn't impact graphics apps, the modset is for the bare terminal.
I had responded incorrectly about graphics applications running. I am able to start freedoom with gzdoom here. There is a warning box popup though. Able to start reTux game. Also. .mp4 video playback seems ok with VLC started through Dolphin.
Another observation is the systray clock is always there. Do you know why systray clock different than other applets?
No, but I've had a hate-relationship with the systray clock and calendar since you can no longer set the font and size for the date an time individually (unless they finally fixed that)
So you think very possible a Plasma 6 related bug of sorts? Not a unknowing user error here?
This is what it looks like to me. Your system is using the Nvidia drivers just fine -- the fact that plasma can't figure out how to use hardware acceleration from your card seems like a plasma issue. There isn't much you can do, you display will either initialize with nouveau or Nvidia. The nvidia driver blacklists nouveau, so you can only be loading nvidia. After you do that, and X starts, or Wayland starts -- whatever, it's up to that software to utilize hardware accel. If it's not, that looks like where the problem is. This is all with a caveat that if your game is relying on Vulkan, there is an issue with older cards not being supported. My G04 Quadro 3000M (fermi) isn't supported by Vulkan at all. I'm not sure about your kepler k600M -- you would have to search "vulkan support kepler". But that shouldn't be the kde6 issue.
Can a Plasma package/s be downgraded possibly? More insight on "Plasma SNAFU" if possible.
Plasma (Situation Normal -- All Fouled Up) [or choose your favorite F...ed] With rpm, you should be able to remove 6 and install 5, but I see that as a dependency quagmire if any dependency isn't' met, etc.. Others will have to chime in on whether this is possible. -- David C. Rankin, J.D.,P.E.
