If the monitor is 280 Hz and the game is 144fps, will the pixel latency results be worse than at 280 Hz 280 fps?

Most likely a noob question, I just saw that monitors are tested at, for example, 280 Hz and 280 fps, and then at 144 Hz and 144 fps. But no one tests at 280 Hz and, for example, 144 fps. Or would the result be the same as at 144 Hz 144 fps?

If you mean pixel response time, which doesn't actually affect input lag (it affects motion ghosting,) then it depends on whether or not you have VRR active. Without VRR, there is no change. With VRR, pixel response will change if the display uses variable overdrive. Without variable overdrive, pixel response stays the same also in VRR mode.

what is variable overdrive?

what is variable overdrive?

Overdrive normally applies the same voltage for the same color transition because the refresh rate is fixed. With VRR, it's not fixed, so ideally, the overdrive needs to adapt to the current game FPS. That's called variable overdrive. Not all displays have it though. I don't know how accurate nvidia's list is anymore, but they do list whether or not a monitor supports it:

If variable overdrive is not supported, the display can exhibit more ghosting when running in VRR mode.

Simply put, higher the frame rate, the lower the latency. Higher the refresh rate, lower the latency.
Here are some nice graphs showing frame rate latency at fixed refresh rate (timestamp included).
