no. 8 bits isn't enough to cover SRGB without banding artifacts (without dithering).

Wait, what? Even with gamma encoding?

yeah (especially in dark areas). On http://www.lagom.nl/lcd-test/gradient.php I can definitely see some in the lower quarter of brightness. It's not glaringly obvious, but it's definitely there.

8 bit is not quite enough, not even for the usual sRGB let alone HDR or wide gamut. This is why jpegli is such a promising new option.
