Describe the bug

import rerun as rr
import numpy as np
import matplotlib.pyplot as plt

rr.init("image color", spawn=True)
img = np.random.random((300, 300, 3)) * 0.2
rr.log_image("image", img)
print(img.min(), img.max())  # to check they are in range [0,1]

plt.imshow(img)
plt.show()

gives

Hovering over the image in rerun shows low RGB values, but bright colors.

Expected behavior
I'd expect it to look the same / very similar with the shown RGB values being the same as those in the raw data.

Desktop (please complete the following information):

• OS: Ubuntu 20.04
