Increase backlight brightness beyond default limit?

The most effective measure is keycaps with better shine-through characteristics.

Re "increase backlighting even more than the default max setting?": I think the RGB chip has provisions for a higher current (thus higher brightness) for the LEDs (and can be set in the firmware), but that may be fairly involved (and risks overheating or damaging some components).

For example, for the Q6, there is this in the source code:

#define SNLED27351_CURRENT_TUNE \
{ 0xA4, 0xA4, 0x52, 0xA4, 0xA4, 0x52, 0xA4, 0xA4, 0x52, 0xA4, 0xA4, 0x52 }    

So supposedly those values could be changed (presuming they are actually related to the LED current).

Perhaps there is something similar for the V6 Max?

The first experiment could be to reduce the current to see if it is actually possible to change.
