Have you tried tweaking the new tonemapper settings with a post process volume? I think the default settings look a bit washed out, but increasing the Slope can help with that. You can also tweak the Toe and Shoulder to adjust the contrast of dark and bright areas respectively. If it’s too dark, try lowering the Toe.
To bring back some color, you could try increasing the saturation of highlights under the Color Grading section. Around 1.2 seems pretty good.
