Disable filtering on LG OLED C7P Game mode scaler?

I feel like this is kind of a long shot, but is there any way to disable the smooth filtering on the internal scaler of the LG OLED 7 series in Game mode?

This is specifically for my older consoles that tend to run games in 720p, like the Xbox 360 and Wii U. I just hooked up the 360 yesterday, and boy does that home screen look rough with the filtering, even when set to 1080p. The Wii U fares a bit better, but really I'd prefer the cleaner look of nearest neighbor/point sampled upscaling, since both 720p and 1080p can be stretched to 2160p using integer scaling.

If there's no way to disable filtering on the internal scaler, does anyone know of an external scaler that would do that without really adding any latency?
