disable pause dim dimming?

I hate that the screen dims (and bar at bottom STAYS up) when I pause something.  I mostly watch britbox if that mattes (is the dimming app specific?).  Whenever I pause, perhaps to read something on the screen, paper/writing clue, etc.  I can't read it.  VERY frustrating.

Ideally, perhaps, NOT dim when initially paused, then just dim after a couple of minutes, or just let the screensaver kick in after a while.

If no way to do this (I have an 4660X ultra 4K box, not a roku tv, TV is an older Sony), is there any way to send feedback to roku to suggest this improvement?

Thanks.
