When using the built-in display-line-number, placing the point at the
last line of the file/end of buffer will make the rest of
the display-number area adopt the line-number-current-line
face. Modifying the face's background thus produces this kind of effect:

Steps to reproduce:
1. emacs -Q
2. (setq display-line-numbers t)
3. (set-face-background 'line-number-current-line "#000000")
4. Go to end of buffer

Thanks, I tried to fix this on the emacs-26 branch with the patch
below.
Fix display of line numbers in empty lines beyond EOB
* src/xdisp.c (maybe_produce_line_number): When the current
line is at EOB, use the 'line-number-current-line' face only
on that single line, but not on the rest of empty lines beyond
EOB. (Bug#33732)
