ultraHDMI Limited or full? To compare n64 video signals

[RIP-Felix]

I've seen sources say that "video games" use RGB 0-255 (Full) and "TV/Movies" use 16-235 (Limited). The more I look into it, the more I'm getting confused. I'm capturing footage and comparing the N64's various video signals, but is it outputting RGB full or limited? I assume the Tink products done't care which it is and just upscale and pass either on. I want to properly compare footage from other products (like the UltraHDMI, Rad2x, Tink2x, & RGB amps). So should I set the UltraHDMI to Full or limited to compare? Limited looks closer to the video I captured via composite and S-video. Also, which way do I flip the switch on my HDretrovision Nintendo cable to get the brightness "correct" for the 64 in Component RGB via voultars THS7374?

doesn't matter as long as your TV is set to the same range.

I opened up the UltraHDMI documentation and RetroActive suggests that Gamma at 1 = no change. It defaulted to 1.3. So I set it back to 1.0 and RGB to full. Now the video I captured looks in line with the Composite, S, and RGB signals I've captured already.

Basically I want there to be no other difference than the method of video signal, no settings getting in the way of comparing the devices. With the ultraHDMI, Limited looked better before I read gamma's default is boosted to 1.3. That's a setting boosting the wrong color space, to achieve similar brightness (not what I'm looking for). Full RGB at gamma of 1.0 should be an unaltered color space, yes?
