Ghostty is less vibrant than Wezterm

[FormalSnake]

Wezterm is on the left, Ghostty is on the right.

I do not know why Wezterm is more vibrant, but this could be a cool configuration option in Ghostty perhaps.

We compare our RGB to macOS native applications like Terminal and TextEdit and in those cases our RGB has always matched exactly. There is one exception: #2125. I don't think WezTerm does Gamma Correction but its possible this is more likely a WezTerm bug than a Ghostty one.
