Reporting that issue is still present in 1.6.14+1.20.4 / 1.6.11+1.20.1. Seems to occur only when using shaders actively with a non-SRGB color space. Hopefully this helps!
Bedrock Edition has it the standard blue, but it should be patched to appear grey (IIRC) when using BedrockWaters--will investigate!
