It doesn't (or the additional power it is so negligible, it is not measurable).
I tested it with the in-game benchmark of "Marvel's Guardian of the Galaxy" on my Steam Deck OLED.
The darker screenshots are with "HDR on".
"low" preset: both 45 fps on average, "HDR on" with a very tiny performance advantage (0.1 milliseconds CPU frametimes + 0.1 milliseconds GPU frametimes), "HDR on" rendered 2 more frames (0.1%):
"high" preset: both 40 fps on average, "HDR off" with a very tiny performance advantage (0.2 milliseconds CPU frametimes, 0.1 milliseconds GPU frametimes), "HDR off" rendered 5 more frames (0.2%):
